Different subnet?

We have a single F5 system here, so my experience with these is limited. This might be a very basic question, then.

 

 

Model: LTM-3400

 

Version: 9.1.2

 

 

Is there something special you have to do to tell LTM to talk to servers on a different subnet?

 

 

 

The Gory Details

 

 

We have an existing Virtual Server that works great load balancing 4 IIS servers - these are VMWare hosts.

 

 

VIP: 206.209.255.41

 

Nodes: 206.209.255.87 - 90

 

 

What we'd like is to create a new Virtual Server that load balances 2 IIS servers (VMWare) on a different subnet.

 

 

VIP: 206.209.255.43

 

Nodes: 206.209.247.9 and 206.209.247.61

 

 

I created the new VS using the same steps I used to create the old ..

 

 

I can telnet to the VIP, port 80

 

 

telnet gsfqa.plexus.com 80

 

Trying 206.209.255.43...

 

Connected to gsfqa.plexus.com.

 

Escape character is '^]'.

 

 

 

But when I browse .. it fails. In FF the error is 'Page Load Error - The connection to the server was reset while the page was loading.'

 

 

When I wget the page ..

 

 

--14:59:23-- http://gsfqa.plexus.com/

 

(try: 2) => `index.html'

 

Connecting to gsfqa.plexus.com[206.209.255.43]:80... connected.

 

HTTP request sent, awaiting response...

 

Read error (Connection reset by peer) in headers.

 

Retrying.
