I have several clients I have setup with VPN (typically Cisco ASA ipsec). Typically when your internal subnet matches the internal network on the VPN it can cause issues, especially with split tunneling.
So... i say that to get to this. I changed my internal network from 192.168.1.0/24 to 192.168.3.0/24 last night. The only immediate issue i found was the DVR stopped working and I assumed it was because of the internal LAN change. I rebooted the DVR and it worked just fine.
This morning while I was at work my wife said it seemed yahoo and facebook were having issues. she was refreshing pages manually. She ran some errands came home, and nothing worked. TV or internet.
I called U-Verse support around 4:45pm. The guy i got on the phone tried to tell me it was because i changed the internal network? Are you serious? I've never had U-Verse and I know the gateway device controls everything but why would the internal network be a problem. Wouldn't the outside interface be what they communicate with? I let him schedule a technician but I went ahead and changed my subnet back to 192.168.1.0/24 (the default setting) and wouldn't you know it the internet started working, sort of. It still feels shaky and sluggish.
TV is a different matter. After changing the subnet back, rebooting the gateway and the DVR plus the other two rooms i do not have a TV signal. The guide just says "Guide Data is currently unavailable".
I have some big concerns here. If I cannot change my subnet on my internal network that's an issue for me. Secondly, is U-Verse really this shaky? So far I like the service but the tech didn't have answer and i can't get the TV back on.

thanks i'll try that. my next task is to get my asa 5510 running behind it. I'm having my doubts now, just seems a little flaky.
If a client called me with these experiences I would be switching them to windstream or the local cable company. Especially after the first tech told me it was because i had changed the internal LAN that he couldn't see my 2wire and the second told me I wasn't supposed to change the internal network at all, it HAD to be 192.168.1.1/24, gateway set to .254. That's laughable if it's true.
