And I have been experiencing MTU issues lately in 012 (as a business user on a fiber connection). For me, going down to 1400 sufficed in solving all the weird connectivity issues I had. I am asking you to try lower because if you're on cables, there are MORE tunnels involved... if it solves the problem, you can go up on a trial-and-error game. HTH, -- Shimi
