DUAL ISP on ASA5505

I need to configure my asa as follows: Two active ISP´s, one(ISP1) for outbound traffic (normal internet traffic) and the other one for inbound traffic(ISP2), http to a web server in the inside network. I have two default routes, one pointing to ISP 1 with metric 1 and the other to ISP2 with metric 2. I perform dynamic nat to ISP1 interface with hosts in the inside network and static nat to ISP2 interface with web server.

Everything works fine with ISP1 but I cannot access my web server from outside..any suggestions?

Thanks in advance,

Laura

DUAL ISP on ASA5505

Hi Laura,

Unfortunately ASA does not support load balancing and you would not be able to have 2 default routes on the ASA, only the one with a lower metric would take precedence everytime. Although there is a document for it on the forum, but it is just a workaround but not a supported configuration. If it is very necessary for you, use it only then:

Hope that helps.
