Hi all,

I have been trying to allow access to a Cisco switch that is behind an
AS3 IPTables firewall, but I cannot get everything to work correctly. I
have a similar problem when going through a Checkpoint firewall.

The guys that administer the Cisco devices use Ciscoworks to access all
of these switches with the exception of the ones in a different DMZ as
the Ciscoworks box. When they do the test to check connectivity,
Ciscoworks tries to get tftp to connect, but cannot complete the
connection. I have allowed a wide open rule to and from the switch and
it still does not work. Does anybody have any ideas?

BTW, I have loaded the ip_conntrack_tftp and ip_nat_tftp modules. Still
not help.

Thanks a lot.
