Re: [pfSense] polling pfsense status for a combined dashboard

2015-01-27 Thread Aaron C. de Bruyn
Forget a dashboard for the moment.  A decent API would go a long ways
for writing automation tools.

I've already recommended to the opnsense guys that they add on an API.

If I only knew a bit more about packaging, I'd make my own fork with
the tools.  ;)

 Strangely enough, I did actually look on the docs site before posting. but

 mind terribly posting a link to the page you mention?

 When I searched the docs site, I looked for 'api', then  'curl', and then
 'header'; but didn't find any relevant results. The closest I found was

 that's not really relevant.


 My apologies, I can't find it now, either.  WTF... I *know* that page used

 As Adam said, I'm pretty sure that there used to be something in the Wiki.
 However, I'm also pretty sure that it was targeted at pfSense 1.x and that
 it was removed from there because something in the 2.x changes broke it.

Re: [pfSense] pfSense Routing - VPN's

2014-05-16 Thread Aaron C. de Bruyn
I have the same issue.  We manage firewalls for a growing business, and
currently everything links to their 'corp' office.  But their corp office
connection is overloaded with all the traffic going between offices.

When I ran plain Linux boxes with Shorewall installed, I wrote a tool
called 'openmesher' that would automatically generate all the link
combinations and create DEB packages to install the SITE-to-SITE.conf file
in /etc/openvpn/ along with shared keys.

Then my boss decided he wanted a GUI to manage the firewalls, so we
switched to pfSense.  Unfortunately there is no API or easy way to automate
the configuration (XML, ugh!)

...but I'm working on modifying openmesher to generate the XML snippet for
OpenVPN configs.  You still have to copy/paste in to your config file, but
it'll still save a bunch of clinking.

I love pfSense, but I *hate* XML and the lack of an API.  The power of *nix
comes from the tools to rapidly edit simple text files and interop through
simple APIs.

*wonders about funding the next pfSense hackathon with an eye towards an
API*

  This is exactly what we do.

 We make the hub the OpenVPN server, and the spokes the clients because the
 hub IP is static, and we can manage all of the OpenVPN listeners on one
 instance.

 If your whole network is a /16, and each spoke is a /24, all you need is a
 route directive on each of the spokes for the entire /16.  In OpenVPN
 Advanced route 192.168.0.0 255.255.0.0;

 You don't need any routing directives on the 'hub' because the addition of
 each connection will take care of that.

 With respect to rules:
 We find it best to make the first rule on the hub's OpenVPN interface this:
 Any source/port NOT destined for THIS hub subnet is allowed to pass.
 That way each branch can manage their ingress policy privately because the
 hub will just route anything not destined for its subnet.

 We also find it best to set up DNS forwarders to the spoke networks, i.e.
 Hub: mybranch.mycompany.com dns dips are at 192.168.11.1.  Spokes can dip
 the hub if so configured which can in turn dip OTHER spokes if so
 configured.  Inverse lookups work too.  For example, add a dns forwarder
 of 10.168.192.in-addr.arpa to allow inverse lookups in the spoke in the
 subnet 192.168.10.0/24

 It's been rock-solid for many years now!

 Good luck.

 That's Cisco's default and others aren't too far from that generally.
 I believe that's something that hasn't changed since originally
 implemented decades ago. Originally, it was likely because networks
 were slow and not switched, so you didn't want to chew up a lot of
 bandwidth just handling ARP. As with many cases along those lines, it
 got entrenched and once a vendor sets a specific default, they tend to
 not want to change it. That's largely educated guessing, as I'm not
 completely sure the reasoning, just that it's been like that more or
 less forever.

 Yes, with modern networks, in a lot of cases it's really not sensible
 to hang onto your ARP cache for hours.

 A number of cable modems are worse than 4 hours. I can think of a
 handful of times over the last 7 years or so, with the most recent
 being a couple months ago, where a support customer got in touch with
 us after trying to move some IPs and messing with it for multiple days
 and couldn't make it work. Packet capture on WAN for the affected IPs,
 check the destination MAC, see something other than the firewall. Ask
 What's this X MAC? The old box we unplugged last week. Power cycle
 cable modem, all is well.

 Hi Aaron,

 Most cable modems I have worked with in the US (on Comcast, Optimum, and
 RCN) all do ARP caching, so you need to reboot them when you change the
 connected device (or you need to clone the old device's MAC address).

 Actually though, working with DSL is worse.  Verizon DSL does ARP caching
 in the Central Office for up to four hours.  I have found that replacing
 equipment hooked up to Verison DSL, it is best to already be on the phone
 with Verizon support to have them manually clear the cache.  At least
 rebooting the cable modem is something you can do yourself.

 I've used Supermicro Atoms with 2 Intel NICs onboard and
 with a dual-port Intel NIC added. I would be also interested in
 suggested list of settings for Intel NICs.

Re: [pfSense] Best practice for SSD installs

2013-06-08 Thread Aaron C. de Bruyn
Just a note of personal experience.  I've deployed ~20 pfSense firewalls
that had SSDs (both cheap and rated 'good' from Newegg) over the past 2
years.  I am not convinced SSDs are more reliable.  Nearly every one has
had an SSD die or become corrupt.  We switched them all to USB sticks and
haven't had any more issues.  Plus it's easier for us to ship a replacement
USB stick to the client and have them plug it in than to have them pop open
the case and replace the drive.

Maybe we've just had bad luck with SSDs, but I'm not convinced they are
ready.

  Which brings me to the question: the last time I performed a pfSense
  'full' install (i.e. not embedded) was several years, and many
  versions ago. What's the best practice when using an SSD? Use the
  CD-based installer to do a 'full' install, or continue to use the
  embedded NanoBSD image?

 Modern SSDs are at least as reliable as HDs. I've used SSDs
 with pfSense for years (including IDE DoMs) with full install
 and never had a failure yet.

  As an aside, there are several options on the Advanced tab
  relating to NIC performance options:
  - Disable hardware checksum offload
  - Disable hardware TCP segmentation offload
  - Disable hardware large receive offload
