(41 (data) ,42 (command), 62 (data) ,63 (command)). The client opens a connection to the server on port 42 and the server tries to open a connection back on port 41.=20 NAT doe snot seem to recognise this, so the application cannot cummunicate with the bank... People using Linux have solved this problem by using the command insmod ip_masq_ftp ports=3D21,42,63 this tells the ftp proxy that it should use extra ports that have the same behaviour as the standard ftp port I dont like the solution by making static NAT routes to only one client, because this limits the number of PC's that can use this application. The application does not have an option for passive ftp. Any ideas? __________________________________________________ "Nothing is as subjective as reality" Reinoud van Leeuwen reinoud@xs4all.nl http://www.xs4all.nl/~reinoud __________________________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
