SNMP through Netscreen VPN

[L. David Leija]

We've deployed 2 Netscreen-10's and successfully established an AutoKey
encrypted tunnel between them. We also utilize the SNMP/Perl monitoring
software, MRTG. We are able to monitor data from the Netscreen on the near
side of the tunnel, however we cannot get SNMP to talk to the remote
Netscreen through the tunnel. We can ping it fine, we also have complete
access to all resources on the remote site through the tunnel. However, SNMP
always gets "SNMP Error:no response received" when trying to establish a
session. Any clues on where the problem is? The VPN tunnel, the remote
Netscreen, or MRTG. I don't thinks its MRTG as it is currently monitoring
countless other devices successfully.
