client dropped after world hands off to zone

[Armm]

Hi,

I have friend who connects to my network via VPN, MTU is 1406.

They can connect to the world server evverytime just fine, however when they create or select a character it prceeds to the first screen about loading zone, then 9 times out of 10 the client freezes. On the server end it shows them handed off to the zone and is there.

Only happens on vpn, i suspect something to do with MTU. If i set MTU to 576 you cant even login to eqemu login server.

Could someone illuminate what is going on here?
