Couldn't you just change the VIP and pool defintions on the LTM to accomodate what you're looking for?

 

 

I'm assuming that today you have a VIP with a wildcard port (0). Just add new VIPs with the same IP and the specific port you want. I.E. from 192.168.1.10:0 to 192.168.1.10:23 for telnet and 192.168.1.10:21 for ftp. Then you just need to associate a pool containing the new server address(es) with the new vips.

 

 

The LTM matches a VIP with a specific port before it matches the wildcard, so conections on 21 would get sent to the port 21 VIP, 23 to the 23 VIP, and the rest to your existing VIP.
