What is the best way to configure the following on a Cisco ASA 5540?

  • I have 2 WAN lines, I need mail (tcp 25) on the one and all other traffic on the second WAN line.

  • On the second WAN line I need to prioritize traffic for some external websites.

I am quite lost in the stacks of documents from Cisco and I have not configured this before. Any help thanks.

Have a budget for this? What type of WAN links are they? – ewwhite Sep 22 '12 at 0:28
Currently two 10Mb ADSL lines. No budget I will have to do this myself with the equipment currently on site. – Shawn Gradwell Sep 26 '12 at 7:45

Answer is simple. Cisco ASA devices are not designed to be routers but rather security appliances. Thus it cannot handle multiple gateways and routes.

I'm sorry but you're completely mistaken... Cisco ASAs handle both static and dynamic routing with no problem; that means they can handle multiple gateways. – Mike Pennington Apr 13 '15 at 9:27
