Hi Henrik, Tried to 'server_persistent_connections off' ... no joy. > Also inspecting the traffic using tcpdump or similar tools to see if there > is any abnormal activity going on should give further insight in what the > problem may be. I ran tcpdump to hope and find some abnormal activity, but to be honest, I don't know what to look for. :-) .. any tips on what to look for or what documents / books I can read to help me understand the problem? Also I noticed something unusual. First let me give you the network layout/configuration. The Zyxel Router Model: Prestige 642 R Router WAN IP: x.x.x.x (not sure) Router LAN IP: 192.168.1.1 connected to a Linux Box using a cross cable. Linux IP (eth1): 192.168.1.2 (GW is the router: 192.168.1.1) Linux IP (eth0): 192.168.0.1 (connected to the office LAN) 150 windows clients with DHCP allocated IP addresses - Rannge of IP Address 192.168.0.21 to 192.168.0.254 - With Gateway & DNS Server IP as: 192.168.0.1 Linux server running Squid following ip_tables line /sbin/iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -d 0/0 -j MASQUERADE The moment this rule is removed, the problem starts up. So do you guys think this is still a problem related to the Zyxel Router due to NAT or is it something related to the Linux server running iptables (NAT/Masq)? -- Regards, Boskey Chheda ���
