Outbound routing based upon source IP

Hi,

 

 

If you define an SNAT pool an associate it with a wildcard routing VS, the BIG-IP will automatically use the SNAT pool member which belongs to the same IP subnet that the selected outgoing router. We've already tried it and it works properly.

 

 

However, if you already have an SNAT Automap attached to the wildcard VS, you'll have to define an iRule based on client IP addresses to assign the correct SNAT pool, but this is an upgrade over previous implementations since the BIG-IP selects the outgoing router and then applies SNAT, not the other way around.
