How I did it was to add an entry into my
netmon seed file for that device. That way, it’ll get into the map no
matter what (as long as it’s a unique IP, that is). I also kept all my
devices in my /etc/hosts too, but that shouldn’t be necessary as long as
your DNS is pretty quick/responsive.

Subject: [NV-L] Monitoring devices
through VPN tunnels
Hi all,
Any advises on the above subject? I have several devices behind VPN tunnels
that I have to monitor for availability as well as configuring events based on
MIB variables thresholds......
I am having some difficulties like:
- some devices (routers mostly) are not being
discovered by NV, but they answer ping and snmpwalk commands issued at the
command line at the NV server.
- different clients connected through VPN tunnels
have similar IP ranges, so the addresses the NV server actually see are
NAT addresses.
How can I work around these isues? Do I have to use CNAT? Is
there any special configuration for NV to deal correctly with devices behind
VPN tunnels?
Most tunnels are configured through PIX/ASA Cisco devices, and some through
routers.
I am running NV 7.1.5 on a Red Hat 4 server.
Thanks in advance.
Best regards,
Mario Behring
