Hi All,
I'm having problems with port configuration of my router WRP400.
I have PC behind NAT with installed firewall on it.
The configuration:
FTP waits for connections on port 21
FTP data port on 4000-4200,
On PC firewall I enable both to be allowed to open.
On router I put Single Port Forwarding FTP to my PC and port range 4000-4200 to my PC
What happens:
Client can connect, when changing to passive mode, the server command
227 Entering Passive Mode (192,168,15,100,15,164) //port 4004
is translated into:
227 Entering Passive Mode (80,238,106,98,19,137) //port 5001
I understand that local IP is replaced by public one, but why the port is changing?
When it comes back to me, it is not replaced back to port 4004, and I have request on 5001, which is stopped by PC firewall.
How can I have FTP on 21 and data packets set on 4000-4200?
Thanks, Tomasz
