Direct connections to a subnet

Hi, I'm hoping I'm posting this in the right forum. Please let me know if I'm not

 

 

Can someone tell me if it's possible to achieve what I'm trying to do and if so how to do it?

 

 

I want to redirect connections to a virtual server to a subnet of addresses

 

 

So for example.

 

I create a VS with address 192.168.1.2 and I want to direct any connections to this to 205.2.2.0/23

 

 

Is that possible? I couldn't see a way to create nodes or pools as as subnet

 

 

Thanks is advance
  • All members of a pool must be explicitly specified. Practically, this is not a limitation because pools have few members [which also need to be monitored before designated "up" and allowed to have traffic forwarded to them, which in your (impractical) example, would imply 510 hosts].

    I was thinking that would be the answer but was hoping not.

     

     

    We have a convoluted network environment; I've have setup an internal server to talk to a Virtual Server on the Big-IP that has a public DNS record associated with it. That VS needs to talk to those 500 odd addresses apparently for an application we're testing to function.

     

     

    I guess I'll have to think of another way

     

     

    Thanks for clarifying though

    You should look into a network forwarding virtual server. When you create a VS instead of selecting "standard" select "Forwarding (IP)" and specify your destination network, in your example 205.2.2.0/23. You'll need to tell hosts on the example 192.168.*.* side of a route to the F5 for traffic destined for the 205.2.2.0/23 network. Hope this helps.

    Forgot to mention, a forwarding virtual server doesn't do any load balancing; at this point it's just forwarding traffic. I'm not sure if that was your intention.

    That Mel.

     

    I had a look at that but I don't think it'll do what I'm after

     

     

    My internal server is on a different network to the Big-IP VS I created.

     

     

    We have a complicated network setup
