Please help: multiple external vlans, same default gateway.

Hi all,

 

We've split a /23 network into 2 IP addresses blocks on 2 VLANs. These 2 VLANs are on different firewall zones. They share the same default gateway/netmask.

 

Is it possible to do that on LTM (we're using 12.1.2), like following?

 

uplink 1 <-> vlan ID 123 (external vlan 1) <-> internal vlan 1 unlink 2 <-> vlan ID 456 (external vlan 2) <-> internal vlan 2

 

I'm thinking of using route domain but want to know if there is better way to do that. Sorry for the newbie question.

 

Thanks a lot.

 

Regards
