Cisco ASA 5505 Security Plus License - Dual ISP
- Thread starter #Chri5#
- Start date
Dual ISP just refers to static route tracking. I.e. If ISP A Gateway is not reachable, use ISP B. It uses ipsla to implement this.
You can have multiple default route's for a very basic form of load balancing, but only on the same interface, so this wouldn't work across two different ISPs.
You need a router in front of the ASA.

To be fair, you're doing something which is technically pretty stupid which is why they don't support it. No decent kit does, it's the draytek market which regards that as a feature rather than the horrible bodge job it is. You won't see Cisco or Juniper or anybody serious pushing that 'feature'.
Load balancing connections from different ISPs is a bad idea. Load balancing any connections is generally a bad idea, better bonding them in almost all scenarios (there are a few equal cost routing configs I use for specific situations but that's generally with multiples of 10Gig and MPLS traffic so not applicable).
