I've got an 1811 router with two DSL connections. I need to seperate the VPN and email traffic, each must go through the designated wan-link. Can I manage that with access lists or is there some other way to do it? Thanks in advance...
Yes you can do this using PBR (Policy Based Routing) which allows you to set the outgoing interface/next Hop ip addresses based on source and destintation IP addresses together with TCP/UDP ports.
Have a look at this config document for PBR and come back with any queries.
