We've just taken charge of a new internet connection with a new service provider. Access is over a coaxial cable and the link is advertised to go upto 100Mbps. We have 2 ISP-provided modems that sync up and work fine.
However, I'd like to change the modems from 'router' to 'bridge' in order to move over some existing site-to-site VPN's from another provider (standard ADSL internet access) using existing CISCO 871's to continue providing the internet firewalling and VPN.
This works fine, except that, to allow us to use static IP Address, we need to create an L2TP tunnel to be assigned the static address (from the modem config).
I have the L2TP authentication and server details from the modem config.
The CISCO 871 is assigned a DHCP address to the WAN interface (fastethernet 4), however the L2TP tunnel does not come up correctly.
My current config is below and I'd appreciate if someone is able to point me in the right direction / documentation to set this up correctly:
description WAN interface to ISP
ip address dhcp
description L2TP dialer to ISP
ip address negotiated
ip nat outside
ppp pap sent-username xxxxx password 0 xxxxx
ppp ipcp dns request accept
pseudowire x.x.x.x 2 pw-class ISP
description Internal LAN
ip address y.y.y.y 255.255.255.0
ip nat inside
ip route 0.0.0.0 0.0.0.0 Virtual-PPP1
ip route <l2tp server ip> 255.255.255.255 FastEthernet4
Thanks for any advice,
