Hi, I'm trying to set up an internal FTP server in a masquerade network. I use the rc.config editor tool, which has the options to set up firewall. In forward, I go in to FW_FORWARD_MASQ_TCP and put the line: 0.0.0.0/0,IP_internal_FTP_server,21 But when I start the firewall I get the error: mfw: setsockopt failed: Invalid argument And the forward doesn't work, but the other services do. Any idea in the syntax of forward services to the internal masquerade network ??
