Can anyone tell me what would cause a computer to intermittently not be able to access the internet, but can ping the gateway?
I have a dual-wan PFsense box. One computer is working fine, but another computer right next to it will sometimes have its internet die. I can ping the pfsense box (gateway), but nothing past that. No DNS servers, internet gateways - nothing.
Here's the kicker - there are wireless routers also on hooked up to the networking and routed through the dual-wan router. If I switch the computer to the wireless network, it works fine.
So, i tried testing the port - and switched the cat cable to a laptop. Same issue. I can ping the gateway, but can't get out to the internet - sometimes. Wait 5 minutes and the internet will work, but still intermittently.
I thought I was overloading the pfsense box, but it's at about 5% CPU usage with 70% memory free. There are about 50 clients on this network simultaneously. (box is a 1ghz PIII with 512mb RAM). Internet usage is primarily for gmail.
Edit: I can also tell you that the internet connections themselves are stable and aren't the cause of the internet issue.
