Hi, I read this articel http://www.cisco.com/warp/public/105/56.html, and was wondering about one thing. Why is it said in the articel that if you change MTU on one client you should change it on all clients on the same network ?
I would think that if all your clients on that network are connecting through the GRE tunnel, they may all have the same issue. If not, I would leave MTU at default.
