I'm trying to configure ASA 5505 to pass FTP connection to Win2003 IIS FTP server on port 58158.
Works fine with port 21 but not any other port.
I get : 227 Entering Passive mMode (192.168.1.10,142,158)
The server sent a passive answer with a non routable address.
This IP is the internal server address.
When I use port 21 the IP address above is the external address ocf the router and everything works fine.
Using static NAT rule Interface inside, server IP address. Translated Interface outside, use Interface IP address.
Enablr Port Address Translation, TCP port 21 to 21 (or 58158 to 58158)
