I have an existing 1800 router that is using NAT and VPN to HQ. I now have a new ISP provider and so now i need to chane the Fastethernet1 IP address. I know how to do that but what else do I need to change to make everything continue to work? Thanks

1) Your own IP and routing
2) The NAT rule that references the public IP
3) Your ACL FIREWALL
4) Your two VPN-peers need to change the IP in their config (and the PSK because that was visible in your config)

Can you please tell me our show me how I would make these changes? Thanks a lot for you're help. The new Outside IP is 70.58.191.193 and the inside IP is 10.0.1.1
Thanks

Basically you just have to replace your old IP against the new one. Delete the old routes and configure the new as provided by your provider.

I just see, that your router is configured for the new IP (70.58.191.193) that you mention above.

Its not in this config but
you don't make it really easy to help you ...
Commands that you don't need/want are removed with a "no" in front of the old command. At least most of the times with some exceptions, and there comes your actual config into play ...

The line
ip nat inside source static 10.0.1.234 72.16.188.235
What should the last IP be in this line? I was thinking it should be my 70.58.191.198 gateway correct?

One more thing please, what command lines do I need to configure the router to use PPPOE and add authentication with an ID and Password. My DSL modem is set to Bridge mode.
Thanks
