Hi all, Im running a small network behind a firewall running iptables 1.3.5 doing NAT. The firewall has two NICs, eth0 for the LAN and eth1 to a adsl modem. Im having problems with iptables dropping some packets that belong to an established/valid connection. I think this only occurs with http/https traffic. For example, if I have a client on LAN browsing somesite.com the connection gets tracked and iptables allows packets coming and going but, and here is my problem, it will drop *some* packets coming from somesite.com . Hence my logs get filled with this packets that should have gone through. As you might imagine this is rather annoying, even more so when I havent been able to find a solution browsing google for countless hours. Please if this post lacks information, let me know and Ill post whatever you need. Thank you, Daniel.
