I am monitoring LAN, WAN1 (ADSL) and WAN2 (3G Tmobile modem) network usage using Paessler PRTG Monitor with SNMP probes. I can monitor LAN and WAN1 input and output traffic (traffic rate and traffic bytes) OK, but on WAN2 I can only monitor incoming rate and quantity. The output rate and quantity is always zero.

If I monitor the SNMP ifOutOctets OID on the Vigor2910VG using the SNMP monitor application; Getif, the result is always zero for interface No.5 (WAN2??).

Is this OID turned off in the 2910VG, or is this a firmware problem??
