>From the limited experience I've had it could be a number of things.   The
SNMP port has to be open to those networks.   Your network configuration
may also come into play.  If you are doing address translation or if those
networks do not reside in your normal address space then you may require
some static routing on your Netview server or firewall or both.    Just my
thoughts.

Subject:  [NV-L] Netmon does not detect connections from or to our Firewall




Netmon has detected the network on our side of our firewall - and with the
help of the netmon.seed file, our customers devices on the far side of our
firewall. However, our map now has two disconnected groups of systems, with
no links showing either the firewall, or the routers on the far side.

We can happily ping and telnet to all the nodes on the other side of the
firewall, but we do not see them in the map. Can anyone say if this is a
firewall problem (ports not opened) or do we need to do something else to
see these connectors.

Thanks
