Load balanced Telnet Servers - Pass through original IP or hostname?

You have to turn off SNAT and route traffic from the Telnet servers back through the F5's, then the request will be from the remote host and you'll see the originating IP. For routing purposes you need to make sure traffic goes back through the F5's.

 

 

If you set your default gateways on the Telnet servers to the F5's you may also want to create a routing VIP so it can get to the rest of your network.
