Hi
My friend had a problem yesterday... he installed pmfirewall and everything was
fine.. However, as I was helping him to set up port forwarding for its internal
server, we had several problems:
The first one is that I could not list the contents of his ftp server, even using
passive mode.
The second has occured when the ftp client was actually trying to find a
workaround to list the files on his computer; it switched ip, using its internal
ip for its server instead of the one te linux router is using.
As you can imagine, the 192.168.x.x subnet is not reachable, so I could not list
the contents of his server. Now I don't know if this behavior is normal or not...
Could it be a general network misconfiguration on his side?
I might add that the goal was to set up a ftp server that would be hosted on port
311 on both the linux router and internal server. In my case, I redirect port 21
to my internal machine, which works wonderfully. Strangely port 311 or any other
port seems to be having problems.
**note**I also forward port 20 (ftp data) to my internal machine.... is this
really necessary?**note**
I understand this is a long E-mail but if anyone can help me in any of my
problems I would appreciate it greatly. Thanks
