Routing between partitions / route domains

Hello, we currently have a f5 cluster configured with two partitions, two vlans and two route domains respectively default route domains for partitions :

 

Public partition with Public Vlan with Y route domain. Private partition with Private Vlan with Z route domain.

 

We would like to know if it's possible to route trafic from publicVS (1.1.1.10) to privateVS (2.2.2.10) to server (3.3.3.10), bypassing our firewalls. So without using the defaut gateway (firewalls) :

 

 

Thanks for your help

  • Hello, thanks for your help. FW in transparent mode & LTM in route mode

     

  • Hi leo

     

    1. Do you want to bypass firewall right?
    2. server fram in routedomain A or B ?

    have a good day!

     

  • Hi, I think you only can do that flow, when you disable "Strict Isolation" on both RD, plus iRule in VS 1.1.1.10 to forward traffic from PartitionA, to another PartitionB virtual server, e.g.

    when CLIENT_ACCEPTED {
       virtual /PartitionB/vs_2_2_2_10
    }

    Maybe is not a good idea bypass a firewall and disable isolation. I think the "Strict Isolation" and firewall should be precious to your network.

    Best regards.

  • Hello, yeah I want to bypass FW. Server farm is in other network (not on any routedomain). The VS on the RD 2 point on the server.

     

    Thanks

     

  • If one uses "virtual /PartitionB/vs_2_2_2_10" to forward the client connection to the inside VS, how do we ensure that the response takes the exact reverse path from RD2 to RD1 without going between FWs? Firewalls are notorious for not liking out of state connections.
