Hi, IŽm having a problem with my iptables. Some users lost connection when they use the iptables as the gateway. Example, they connect with the msn messenger and after some time (a few minuts) the conection go down, and then after a few minuts they reconnect automatically. This happend with others applications too, not only with messenger. Can this be a problem with ram memory? May be someone had experienced the same problem and can help me. Thanks in advance. Pablo.
