setting up Cisco 2811 internet connection

[lordkiron]

We just moved to a new place and ISP here have a bit weried connection - they use cable modem that provides "local" IP (through DHCP) to the router and than you have to dial out L2TP to the ISP in order to connect to internet.

This setup works fine with "home" routers, like the LinkSys, however I have no clue on how to setup it on 2811.

Can someone help me?

Thanks in advance,

Roman.

Hosts---- (e0)2811 ( e1)----cable modem

On int e1:

ip address dhcp

ip nat outside

On eo:

ip address x.x.x.x

ip nat inside

ip route 0.0.0.0 0.0.0.0 dhcp

(else if u have the ip address on cable modem , you could use it as next hop)

Ip nat inside source list 1 interface e1 overload

define the access-list

Let me know if this works!
