SNAT Automap, INET Port Exhaustion, and Self-IPs

It actually can use non-floating addresses for SNAT automap, but there are some VERY significant caveats to this. The affinity for a floating address is so strong that it is chosen over the fact that an address is on the correct egress VLAN. SOL7336

 

 

So, if you have _NO_ floating addresses on you box at all, you can use the non-floating addresses for SNAT automap. If you hove a floating address on some VLANs and not others and the egress VLAN is one that does not have a floating, SNAT automap will choose the first floating address listed in your config and use that.

 

 

When there is a floating address(es) on the egress VLAN SNAT automap will only use the floating address(es) on that VLAN.

 

 

Hoolio's suggestio nfor avoiding port exhaustion is on the money.. SNAT pool or additional floating addresses.
