My Linux Router Seems To Be Working Slowly
First of all, I will explain my network set up: I have two computers, one videophone and a PS3 that is connected to my 1 gbps D-Link switch. Also, Eth1 interface on my Linux router is connected to the same switch. Eth0 on the same router is connected to my private's apartment network.
I'll use ASCII illustration below to help you understand my network topology a little better. Computer #1, Computer #2, PS3, Videophone --> Switch --> Eth0(Router)Eth1 --> Another gateway inside my private apartment network. I use Iptables on my router to serve as a routing service and firewall on for my hosts in my own network. I had no problem with it for a while. This changes when I noticed that both of my systems takes so long time to load web sites and establish connections in my games. I temporarily solved the problem by rebooting my router. However, it would come back few hours later. I rebooted my router to make problem disappear again for only few hours. I am trying to find anything what is wrong with my router. I tried to look at how much my router's memory and CPU is utilized using top command. Also, I ran the ping test only to find latency level to be normal. I ran tcpdump to see what the network traffic is like, when it goes through my router but I couldn't find any strange. I tried to find anything that may raise red flags in /var/logs but I found none. I am a little lost on what else to investigate and fix the problem. I hope you can give me a good direction on what to do next to fix the problem so my hosts inside my network can run more smoothly when it is connected to Internet. |

Please do NOT post the iptables script until we ask you to; & then put it in a pastebin or your LQ blog, but don't break the train of readability of the thread by putting it here. Quote:
Was there any change to it just before this trouble began? Quote:

How fast is the CPU & how much RAM do you have? FWIW, My SmoothWall Express 3 box has 128k at 200MHz. Quote:
