I have a problem I hope some people on this list could shed some light on.
Site A has the following:
Packet filtering firewall with stateful inspection forwarding port 21 to a
MS FTP server.
Site B has the following:
Checkpoint FW-1 forwarding 21 to MS FTP server.
Site A can connect to Site B via DOS FTP with fully functional data and
control sessions.
Site B can connect to Site A via DOS FTP and not achieve a data connection.
Only log in.
Does this have anything to do with an Application proxy, if that is what
FW-1 uses.
Hopefully this info isn't too sketchy. I can elaborate if needed.
Any hints, recommendations, URLs, or one-liners would be appreciated.
Thanks in advance,
Shane
