Dual WAN configuration on Cisco 2811 (ADSL and SDSL)

Asked by localgareth in Network Routers, Cisco PIX Firewall, Network Design & Methodology

Tags: Cisco, Router, 2811, c2800nm-advipservicesk9-mz.124-1a.bin

Hi

I have a Cisco 2811 that we use with a an SDSL line (connected via a SDSL modem to FE0/0).

We have three IPSEC site to site VPNs, and a PPTP dial in VPN configured (which is all working fine).

We have installed a ADSL interface card and ordered an ADSL line with a view to using the SDSL for VPN access between three sites, PPTP dial in VPN, incoming http, smtp for our extranet and mailserver. We want everything else (mainly web surfing) to go via the ADSL connection.

The SDSL line is 2MB uncontended, which is ideal for VPN and customers access to the extranet. The ADSL is 8MB but less reliable, but is fine for web surfing, as we don't want people cripping the SDSL line surfing tube sites all day.

Hopefully this can be achieved without BGP, maybe just with some clever routing? It would also be useful if I route everything to the SDSL line (for when the ADSL line goes down)... ip sla maybe?

See attached config.

Any help would be greatly appreciated.


Gareth
