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
