Okay - so y user wants to have 16 usable IP addresses - so I woul have to
subnet with 255.255.255.232 - right.

So if I subnet as per the above mentioned mask it should be okay.

On ALLL my portmaster right??

Yet it doesn't matter if this address is in the subnet? Is this the IP
address of the PM port? or is it the address of the remote system? I'm am
confused as to who gets this IP address.

I thought the IP route told the Cisco where to route a specific set of
addresses? This seems to say "Route the 196.7.162.8 addresses - looking
at a netmask of 255.255.255.248 - through 196.7.162.8. This seems odd -
shouldn't you tell the Cisco where to route the 196.7.162.8 subnet to?

Thanks Colin - now if I can just get it to work.

BTW: I set one ip route in my Cisco that was incorrect and can't for the
life of me seem to get rid of it - whats the Cisco command to get rid of
an ip route?
