Is there somebody from MSN here? Is there a workaround for this 
problem without using other type of tunneling? If not, is there any 
other workaround?

Use "ip mtu 1500" on each tunnel interface. Uses more CPU but works.

"ip adjust-mss 1300" is also nice, in conjunction with the above you end 
up with the TCP traffic not being fragmented and it still being 
transparent for fullsize UDP traffic.
