I have a pair of ASA 5520 and I'd like to configure it as failover with my 2 ISPs. We have purchased a subnet from each ISP (they are 64.x.x.x/30 and 11.x.x.x/30). My question is how do I configure 2 x ASAs with 2 difference ISPs for failover ? Thanks a lot.
Note: the pair of router will do all the NAT and routing parts.
