IP forwarding

Setup:

 

Vlan 200 10.200.1.80/16 Vlan 100 10.100.1.60/24

 

I need to IP forward 1433 traffic from 10.200.1.80/16 destined for 10.100.1.60/24

 

How do I configure this? What are the DGWs of my servers?

    Just noticed your DGWs question.

     

    Your source servers will need to have a default or network route (10.200.1.60/24) in their routing table pointing to the F5.

     

    Likewise the destination servers will need a default or network route (10.200.1.80/16) in their routing table pointing to the F5, or alternatively you can specify a snat (automap or a pool) in the network virtual server to force return traffic to the F5.

    Create a Forwarding IP or Performance L4 network virtual server.

     

    Specify ;-

     

    Destination 10.200.1.60 255.255.255.0 Service Port 1433 Enable on vlan_200

     

    You do not need to specify a pool as 10.200.1.60 /24 will be in the routing table already as an attached route.
