Re: [H] IP address translation question..
Hey buddy, long time no chat, hehe. The script is encrypted so I have no idea how it is set up. The jist of how it works is here http://nerdvittles.com/ and it's called the "travelin man". I suspect the problem is with the SIP client on my phone, and the reason I suspect that is because the activation login on the centos system does list the proper IP address that has been authorized, but when I try to connect as the second step, the SIP client is denied due to ACL issues because it is listed as being my home IP address and not the remote address that was approved. I'm going to try a different SIP client and see how that fares and I'll let you know.

[H] FIOS question 2.5?
I am not fully up to this level yet. I've gotten alot of offline suggistions (mostly about tangential wiring my home AND selecting FI-TV). Fine. FI-TV is not my focus ATM. I accept that I may get an RJ45 interface (ethernet) to a future ONT. ATM, I have no idea WHAT comes out of this RJ45 interface. IS it acceptable for me to question my 'pending future' ISP about THIS, AND, things like: (YES, all below is stuff from my Router set for xDSL!

[H] IP address translation question..
I'm using a new script that temporarily creates a firewall rule to let an outside connection in on a centos box. I'm having a problem because the box sees the IP address of my router 63.193.xxx.xxx, instead of the IP address that has been granted rights 70.91.xxx.xxx. I'm not sure whether the problem is at the router or if it is related to the software that is connecting to the box (Android Sip client -sipdroid) Any insight or input is appreciated. When the script hits the centos webserver it is identified correctly, but when the SIP client tries to connect it is denied because it appears to be the routers IP addy instead of the external one. lopaka
Re: [H] How bad will this get for Dell?
OK. Like this different from similar practices of Intel, HP, Compac, AMD, Motorola, Micron, GateWay, IBM, etc? Some bad stuff got out of the factory? If Dell has gross amounts of spare parts (their expense), small noise. If Dell has NO amount of spare parts (or plan), very big noise. This one will be fun to follow, however. Seems like we all like to beat up on Dell! And, maybe, because I use a Dell monitor and Dell switches (2)... :) And, they run great. I'd buy them all again.

When the TELCO has monopoly status, it has freedom to invade my LAN and tell me all manner of traffic it finds questionable. Just the current field of play ATM. No harm, no foul! Now that I fully understand your UK perspective, your points provide some things to think more about. My primary firewall lives at my Router. I chose my Router for the on-board SPI. My previous Router did not offer SPI; it was NAT only. Can you tell me what SPI is ? My understanding is that SPI is defined as "Stateful Packet Inspection." I am not capable of explaining this. I have spent some years reading and trying to understand the logic behind it. I understand just enough of this feature to decide that NO Router product should live at my IP Addy that does NOT contain this feature. It is a new feature since I was schooled in the Internet back in the 1970's. I'm lead to believe that it is a stronger form of 1st line protection; prior to my Router's firewall logic; and, in concert with NAT. No, I do not fully comprehend the science or logic. Yes, I do see and accept that it seems to work! (via WireShark!) Others may have other views/opinions. In this sphere, I am NOT an expert. I just use/buy the feature. I replaced my older Router (Netgear RT314) just to have this SPI feature. Yes. I do use the internal client WinXP firewalls also. I thought I had a strong set of Router Inbound Rules set/allowed.

Re: [H] Virtualization Certification
Well, as I said, I am using Xenserver at home right now and since it is free, have managed to get a copy of it running in my office. We had a requirement to run 2 servers for development but had 1 physical box. I managed to convince the management to upgrade to 8 gigs of ram for that box and now we can run 2 servers in 1 physical box. So everyone is mucho happy and the developers really don't notice much speed difference. Anyway, no this is not work related, I just wanted it perhaps to be a career path for me.

Hey guys, I downloaded Citrix XenServer 5.5 about 6 months ago and have been using it heavily at home for several purposes. Bottom line is that I'm now hooked on virtualization. It's an awesome technology that really has a bright future. I was thinking of some sort of certification in virtualization. Perhaps that could be a future career path for me. I know VMWare is the industry 800-pound gorilla, but how does everyone thing about Citrix certification? Is it worth the time and money or should I spend it on VMWare certification?

If you have the router firewall switched on and NAT switched on its not in "Bridge Mode"' On 6/29/2010 12:14 PM, Gaffer wrote: Hi Josh, On Tuesday 29 June 2010 08:00:18 Josh MacCraw wrote: Uh Gaffer needs to read& process the info better! The only "bridge mode" here is on the *DSL MODEM* which is where the *ROUTER* sends the PPOE credentials (if even needed) instead of the modem resulting in a live IP on the router's WAN port instead of being double NAT'd. Would you care to clarify your comments. On 6/28/2010 3:47 PM, Gaffer wrote: Hi Duncan, On Monday 28 June 2010 21:50:10 DSinc wrote: Gaffer, My replies are inline TNX, anyway.

Well, as I get smarter and answer my ?many? questions (another thread in play!) I am beginning (again) to have trouble with my xDSL connection. I suspect someone local (or ?) keeps camping out on my assigned IP addy from my ISP so that they can just dick with my xDSL modem or my Router. I know I have my xDSL modem set to a "bridge" mode. I suspect this makes it a straight wire connection to my Router's WAN port. I would never use "Bridge Mode" unless I was feeding a box that was specifically setup to be a firewall, something like "IP Cop". Should I NOT use "bridge mode" in my TELCO-supplied modem I would be Double Nat-ng and have 2 firewalls. If you are using your router in bridge mode then it is not doing NAT or firewalling. Just because Wins has what it calls a firewall has nothing to do with NAT. I view this as excess overhead. Perhaps my bad. My router does both NAT and supports its' own firewall and SPI. Both of these selections have been activated since day one! You can't have it both ways ! If you have the router firewall switched on and NAT switched on its not in "Bridge Mode" I think I have my Router as |strong| as I currently comprehend its' directions. Your router is not being used as anything but a modem. Its most valuable assets are being thrown away by it being configured as it is. Can you please share some more logic to this? I believe that my Router is my single point of 1st protection to Inbound stuff. Or, perhaps you and I are "wired" differently. This comment I do not understand. I doubt that we are "wired" differently. :-) But you are right, the router should be the 1st point of protection. If you really have "Bridge Mode" turned on, then its simply a modem without offering any protection. All "Bridge Mode" does is pass on the IP address that the ISP assigns to your connection. Turns out, I have to save Router logs and reboot the Router about every 3-7 days to recover a semi-firm connection. The Router is a DLink DGL-4300. All wireless is disabled. I use wired LAN only. I use a Dlink router. I have mine set to firewall and NAT. The firewall blocks all unrequested incoming traffic and lets everything out. NAT allows me to use a range of IP addresses that are not Internet routeable effectively allowing the use of several machines from the single IP that my ISP assigns me. Which incidentally changes each time I restart the router. OK. Understand this logic. Same-same. That's how life is here too. The problem is I have to re-boot the Router several times a day! This is a totally different issue ! This could simply be a noisy incoming line providing a weak noisy signal. In fact a weak noisy signal to the router could be anywhere between the CO and the router. Or it could be that the router is dieing. I've replaced my router several times because its performance has become degraded, probably due to high voltage transients on the telephone line feeding it. I've also had the spark gaps replaced because they have been damaged during thunder storms. Is this possible? Do not know why someone local chooses to pick on me? I will suppose giggles and laughs for the present! This is the same view to me as past electrical storm interference I had with an older (retired) xdsl modem.
