I am using CentOS 5 in my environment and it acts as a gateway for my LAN. My eth0 interface MTU is set to 1500 (default).
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
Recently I am facing a strange problem where some of the websites simply hangs. If I change the MTU to 1492 the same websites open in the browser but then SSH connections hangs at that time.
What could be the problem and how do I fix it ?
