alg.exe and FTP server

When I start windows 2003 SP1 (with firewall enabled and exception defined
for port 21 and inetinfo.exe process), my ftp server (IIS 6) cannot accept
ftp inbound connection (passive mode) . If I stop, and then start, the
process ALG, all works fine.
All other services work fine.

What can I do to solve this problem?

thanks

What is the ALG service?

Ok, but this doesn't help me to solve the problem. Why FTP works only when I
stop-and-start this service?
