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
Thanks a lot.
