Hi,
Sorry for my very bad english. ¿Can you speak spanish?
I publish a Microsoft FTP Server through Cisco PIX 515E with static PAT. In active (port) mode works fine, because in passive mode any command receive response and a time out is received. I use fixup command for ftp to port 21. The static pat redirect ports tcp-udp 20 and 21, and access rules permit trafic to ports TCP-UDP 20 and 21.
What is my problem?
Very thanks, Diego Fernández
