Squid + IPtables + FTP

[Patrick Lankhorst]

Hi,   I have a strange problem: I have Squid 2.4 running, and an IPtables firewall, both on the same RH 7.2 box. The box acts as a router for 1 win box. When both squid and the firewall are running, I can access every FTP site I like. However, when I stop the firewall I can't reach any FTP site anymore. IE waits for about 2 mins. then it seems to reach the FTP-site, but then, after 30 secs., comes with a timeout message. When I start the firewall script again, everythings fine again. IE on my win box is configured to use the proxy for all protocols.   Notes: The firewall is configured for masquerading (due to games not working through the proxy) and when i stop the firewall script the last two rules are:   iptables -F INPUT iptables -P INPUT ACCEPT   Thanx Patrick
