Solved: ASA 5510 with two WAN links

alex goshtaei · ‎01-20-2010

Hi All,

we are using ASA 5510 with two WAN links. I was trying to configure IP SLA to setup link redundancy. but with this mechanism, we can't use both link at a time, since ASA doesn't support PBR. Now we want to come up with static route to pass certain traffic from first link and other traffic from primary link. is it possible to achieve this configuration? for example pass all traffic from web and ftp servers from primary link and pass the rest from backup link.

any suggestion would be very appreciated.

Thanks

Alex

Hi Alex,

This has been addressed multiple times in the forum. The ASA does not support dual isps or pbr, so it can't be smart enough to send traffic destined to one host out on one link and the rest on the other.

If you had a router outside and inside of the ASA you could configure pbr to get you past that obstacle.

But unfortunately the ASA cannot do it.

I hope it helps.
