Client connecting via powerline ethernet is having problems

Post by warbux » Wed Jan 23, 2013 7:15 pm

Hi I have a simple VPN setup for a few clients and one of them is suddenly having his internet crash every couple days. I think its interference because its only happening to him. Currently MTU is set at 1500 I have quite a few clients on there so I don't want to interrupt all of their service unless its something I need to do but I am thinking I might need to lower this. Here is my config and the logs.
  • port 1194 #- port
