Can't forward more then 3 ports to an IP

post #1 of 10
Thread Starter 
I'm having a baffling issue.

At my company our Server can't seem to have more then 3 ports forwarded to it, I thought it was our cheap residential router. So i built a router out of an old PC and installed IPcop on it, and either i configured the FTP wrong (which last i checked it used port 21, IPCop agrees) or the computer it's self can not take the traffic..

EDIT: Windows Firewall had FTP blocked, i allowed all traffic for FTP (which i assume in Windows is port 21) and still no dice.

EDIT2: manually added the port and it's working fine, But i'm getting an error 425

Alright, port 20 is the problem port. However i can't seem to wrap my head around the issue.

It's forwarded the same as Port 21 in my router to the server IP. and i allowed it through the firewall, the same as i did 21. And canyouseeme.org can't see me

If i disable the firewall on Windows i get a connection refused on Sanyouseeme If it is enabled i get "Connection has timed out" if that information helps at all.

EDIT: Added 20 and 21 to outbound Firewall rules, and still nothing.

sounds like you have the rule applied backwards
should be
permit any (192.168.1.1 replace with your Server's IP) eq 20, 21

Is the ftp server active or passive?

Also from the outside do

Telnet serverip 21

See if you can get to get to the server, if not the forwarding isnt right or there is a firewall inbetween you and it smile.gif

I'll telnet once i get home tonight, Can't now since i'm on the LAN. The only firewall is the router i have (which has the ports forwarded to the server) and Windows built-in firewall. that i have told to allow ports 20 and 21 at all times, always (both TCP) the server i believe is in passive mode

Are you forwarding AND opening the ports on the firewall?

~~~~~~~~
Is the port already assigned to another NATed IP? You can't forward the same port to 2 NATed IPs.

EG:

Port 23 to 10.0.0.1
Port 23 to 10.0.0.2

This is an invalid entry.

I'm pretty sure it's the firewall. I'm using FileZilla, Of which i am not held down to, if there is another, better, FTP software, i'll gladly switch.

Port Forward settings in the router, both are forwarding TCP
