Bogus routes with regional free pool depletion (was: Re: The Cidr Report)
Folks - As noted in a prior message to the "nanog" mailing list, it is quite likely that some of the address blocks listed in this CIDR report under the heading "Possible Bogus Routes" will shortly be issued to requesters. In the case of unassigned blocks in the ARIN free pool, this is expected to be in the second half of this year (2014). If you are currently sourcing routes for one of these address blocks, it may be prudent to start reviewing the basis for doing so, as any issuance would likely result in unexpected operational impacts once put into use by the recipient. If there is some confusion regarding the registration status of one of these blocks, then having the current party making use of the block raise the issue with the respective RIR would be a wise proactive measure.

Regional IPv4 Free Pool Depletion versus "Possible Bogus Routes" section of The Cidr Report
Folks - Several of the "Possible Bogus Routes" in the weekly Cidr report appear to be from address blocks which will be issued as we get closer to the end of the IPv4 free pool in each region. In the case of ARIN, this is expected to be in the second half of this year (2014). If you are currently sourcing routes of one of these address blocks, it may be prudent to start reviewing the basis for doing so, as any issuance would likely result in unexpected operational impacts once put into use by the recipient. If there is some confusion regarding the registration status of one of these blocks, then having the current party making use of the block raise the issue with the respective RIR would be a very wise proactive measure.

ROFLMAO Party in Bellevue is more than likely to push it back up over 500K
again, isnt it?
Sounds like a Dish commercial
(James Earl Jones voice):
When you put a bunch of network engineers in a party in Bellevue, you get a
bunch of drunk network engineers.
When you get drunk network engineers, you get interesting router
configurations.
When you get interesting router configurations you get disaggregation of the
routing table for TE.
When you get disaggregation for TE, the routing table grows.
When the routing table grows, you hit half a million routes.
When you hit half a million routes, the internet starts to break.
Dont break the internet. Dont get half a million routes. Dont let network
engineers party in Bellevue.
(No, Im not actually opposed to the party, but I thought you might find the
commercial amusing).

Re: The Cidr Report
w00 h00! We did it!!
Is this excellent or what? We dipped below half a million again! I am impressed.
Keep up the good work, everyone.
Party in Bellevue if we can keep it below 500K until then!

But in a carrier-grade NAT implementation that serves say 5000 users, when happens when someone from the outside tries to connect to port 80 of the shared routable IP ? you still need to have explicit port forwarding to specific LAN side hosts (like the web server) right ? Trying to be devil's advocate here: (and discussing only incoming calls) That's the problem with your devil. The first outgoing connection negates every protection you've assumed with one-to-many NAT. What you really need is a policy that says explicitly what traffic is permitted in each direction. established/new outbound is the problem in this scenario, not what internal addresses you use. On a secure server LAN, the ideal configuration for outbound would only allow connections to update servers you control, and acknowledgement traffic for protocols you are allowing inbound. In a NAT setup for a company, wouldn't the concept be that you explicitely have to open a few ports to specific hosts ? (for instance 80 points to the web server LAN IP address) All the rest of the gazillion ports are blocked by default since the router doesn't know to which LAN host they should go. On the other hand, for a LAN with routable IPs, by default, all ports are routed to all computers, and security then depends on ACLs or other mechanisms to implement a firewall. Auditors probably prefer architecture where everything is blocked by default and you open specific ports compared to one where everything is open by default and you then add ACLs to implement security. Blocked by default or allowed by default are just concepts on a firewall. People make the mistake of thinking that allowed by default is the default, but that's only true of the underlying host OS, and only if that host OS isn't hardened. Specifically, ip forwarding shouldn't be turned on until needed. Linux doesn't turn this on by default, so by default you don't permit routing no matter the source or destination IP addresses. The mistake that everyone is making is they think with NAT, secure rules are easier to write so getting the firewall online for the first time is easier, and maintaining it is easier. The problem with this statement is it's only true to a certain extent. If you care about whatever you're securing at a PCI/SOX level then NAT bought you nothing. You still need to write secure inbound and outbound rules. If whatever you're securing doesn't have to be that tightly controlled then NAT buys you a little, but it comes with a glaring false sense of security. I know at my office the IT department has dealt with several worm outbreaks that spread through email and then use the local LAN to send outbound port 25. I had to block port 25 outbound for the corporate network when it became apparent that IT was using "NAT is a firewall" as their security methodology. (Not judging whether one is better, just trying to figure out why auditors might prefer NAT). Also, home routers have "NAT" which is really a combo of NAT with basic firewall, so if you don't have "NAT", they may equate this to not having a firewall. Auditors prefer NAT because everyone in the world understands security and computers on different levels. You don't know if you're getting an auditor that writes their own pen-test suites or just runs nessus and prints the results. They may have been trained by someone who developed the "intuitive" logical understanding that NAT systems fail-closed so they're better for defense in depth. The problem with this is, as stated above, it's not buying enough to be worth it and it causes a false sense of security. They may have even reached this conclusion themselves and it's hard to convince someone their ideas are wrong. Honestly they aren't even wrong, they're just picking a battle that shouldn't mean as much as they think it does. Ideally, your security group should have unit-tests or just a network monitoring process that nmaps from both directions. On inbound there are PCI compliance auditors that will do this for you regularly so that you can be assured the protection is still there. Outbound you need to be just as vigilant to make sure the rules are just as strict. Ultimately, things like CGNAT are completely ineffective for security because the outbound rules have to be wide open so people can use it.

But in a carrier-grade NAT implementation that serves say 5000 users, when happens when someone from the outside tries to connect to port 80 of the shared routable IP ? you still need to have explicit port forwarding to specific LAN side hosts (like the web server) right ? Trying to be devil's advocate here: (and discussing only incoming calls) In a NAT setup for a company, wouldn't the concept be that you explicitely have to open a few ports to specific hosts ? (for instance 80 points to the web server LAN IP address) All the rest of the gazillion ports are blocked by default since the router doesn't know to which LAN host they should go. On the other hand, for a LAN with routable IPs, by default, all ports are routed to all computers, and security then depends on ACLs or other mechanisms to implement a firewall. Auditors probably prefer architecture where everything is blocked by default and you open specific ports compared to one where everything is open by default and you then add ACLs to implement security. (Not judging whether one is better, just trying to figure out why auditors might prefer NAT). Also, home routers have "NAT" which is really a combo of NAT with basic firewall, so if you don't have "NAT", they may equate this to not having a firewall.

Care to comment on how you feel about the COI that developed between AA Consulting business at Enron and AA auditing Enron? Not asking you to disclose anything confidential, but if you have wisdom to impart about any sort of generic lessons learned, etc. that might be relevant to this discussion, I think that could be useful.

I thought about posting in the super-large anti-NAT/statefull firewall thread a few weeks ago but decided it wasn't worth it to stir up trouble. Here is some trivia though: Back when Slammer hit I was working for a major NSP. I had gotten late dinner with a friend and was at his work chatting with him since he worked the night shift by himself. It became apparent that something bad was wrong with the Internet. I decided to drive to my office and attempt to do what I could to fix the issues. This was a mistake. Because of corporate reasons, my office was in a different city from the POP I connected to. I was 3 hops away from our corporate firewall, one of which was a T1. We had access lists on all the routers preventing people from getting to them from the Internet, so I thought my office was the only place I could fix the issue. Well, someone had put a SQL server in front of or behind the firewall, somewhere where it would cause fun. That DOS'd the firewall. It took 3-4 hours of hacking things to get to the inside and outside routers and put an access-list blocking SQL. Once that was done the firewall instantly got better and I was able to push changes to every 7500 in the network blocking SQL on the uplink ports. This didn't stop it everywhere because we had 12000's in the core and they didn't support ACLs on most of the interfaces we had. The access lists had to stick around for at least 6 months while the Internet patched and cleaned things up. Fun fact: the office network I was using pre-dated RFC1918 so we were using public IPs. The software firewall that fell over either did so because statefull rules were included for SQL even when they weren't needed, or it died due to pure packets/sec. Regardless, all of the switching and routing hardware around it were fine. This isn't an argument against firewalls, I'm just saying that people tend to put stock in them even when they're just adding complexity. If you have access lists blocking everything the firewall would block then you might think having both gives you defense in depth, but what it also does is gives a second place where typos or human error might cause problems. It also gives a second point of failure and (if state synchronization and load-balance/failover are added) compounded complexity. It depends on the goals you're trying to achieve. Sometimes redundant duties performed by two different groups gives you piece of mind, sometimes it's just added frustration.
