Hi,
I have just replaced a cisco router in our WAN with FW1. We are
migrating to seperate NIS domains etc.
Two immediate problems came up. My Lotus Notes clients lost connection
to the Lotus Notes Server on the other side of the firewall. We dug up
the port the Lotus Notes server listens on and thought we would get a fix
by opening a hole in the FW until we could physically move those systems.
Didn't work.
Also, the perl script we had written to open a socket on servers for
backup is failing as well. In the cisco days, I had an permit statment
in place for a port number over 1024 to allow the backup over the router.
It worked, but what seems to be happening is this case is the FW is
remapping the ports and hence loosing the connections. We go out of the
FW on port XXXX but come back on YYYY.
I have no experience setting up these types of services over a firewall.
It would appear that the FW is doing what it was designed to do. We are
still setting up service for this FW from Sun.
Has anyone setup a Lotus Notes Server and Lotus Notes Client with a FW
inbetween the two systems? Is anyone backing up servers through a
firewall?
