Means the clients is trying to use a port that is already defined within
the services file.  Firewall, by default, will not allow known service
ports to be utilized by ftp servers.

Subject: [FW-1] Ftp inbound error

Anytime a client behind our firewall tries to establish an ftp
connection
inbound, a connection reset error occurs on the client.

I checked the logs and noticed a rule 0 drop (implied rule), with this
tidbit in the info field "reason: tried to open tcp service port, port:
pptp-tcp"

What exactly does this error mean ?

Thanks in advance,

CF
