Hi,
I'm trying to pass SNMP traffic through a Linksys WRT54G router, but the only way I can get it to work is to put my PC (running the MIB browser application) on the DMZ. Nothing else I've tried has worked (port forwarding and port triggering) - the SNMP replies from the remote device don't get through the firewall. What rules do I need to create in the firewall to allow this traffic?
Thanks, Nick
$ grep snmp /etc/services snmp 161/tcp snmp 161/udp snmptrap 162/tcp snmp-trap snmptrap 162/udp snmp-trap snmp-tcp-port 1993/tcp #cisco SNMP TCP port snmp-tcp-port 1993/udp #cisco SNMP TCP port $
I'd put my money on 162/udp. You can finding out for sure by performing a protocol analysis on the PC while the application is properly functioning.
