ASA Routing based on FQDN and TCP (UDP) ports

Hi Everyone,

We need to accomplish a routing behavior wherein ASA will route a particular traffic based on FQDN and/or the service (tcp, udp) its using to reach the FQDN. I have attached a diagram for reference. If this is not supported under ASA (alone), what solution do i need to accomplish this? Any ramifications on terms of routing if do this?

I am not so sure about the FQDN part but forwarding based on port numbers is achieved using Policy Based Routing and Cisco does support PBR on ASA with sufficiently recent OS.

Hi Richard,

Hi Richard,

Thanks for the idea. It's working

here's the config applied

access-l ROUTETHIS  ext per tcp host THEHOSTS obj  FQDN eq 22

access-l ROUTETHIS  ext per tcp host THEHOSTS obj  FQDN eq 21

route-map ROUTETHIS per 10

match ip add ROUTETHIS

set ip next-hop ISP2_GW 

int INSIDE

policy-route route-map ROUTETHIS

Thanks,

Jon
