MRTG is not able to identify a match for this. I assume the interface actually exists at the moment? Some systems will only create the interface in the SNMP when it is actually up. If this is the case then you don’t need to worry as you'll just get 'unknown's while the interface is down. Can you run MRTG to check while the interface is up?
What device is this gw box? It seems to be behaving oddly. If it’s a cisco, try the 'persist' option mentioned by the other poster, might help (I've only ever monitored a ppp interface on a Linux box and there it is permanently visible)
