Virtual Route Table for VS

Is there a way to create a separate route table for a VS?

I have devices that are local to the LTM that need to FTP to a new VS. My existing configuration requires using 10.206.173.1 as the default gateway, however the new VS requires using 10.206.0.1 as the gateway. I cannot modify the routing table because the same devices at the remote location use my existing VS via the default gateway 10.206.173.1.

I am using the following iRule to perform the SNAT on the new VS which is working.

when CLIENT_ACCEPTED {

snat 10.206.0.251

}

My issue now is that I have an asymmetrical routing situation. The SNAT (10.206.0.251) is routing out the DG (10.206.173.1) and then the return traffic is coming back on the 10.206.0.0/22 interface.

Sources: 10.206.0.135, 10.206.1.50, 10.206.173.129 VS: 10.206.1.245 Pool Members: 10.249.1.59, 10.249.1.100

I attached a diagram that may help...

Here's the ascii art inline:
