MikroTik

I have problem connect to L2TP server. This is MT <-> MT L2TP connection, whitch work on 2.49.xx version !
When I change MTU and MRU under 1270, connection work well, but from my notebook doesnt!

One of more connections write to log - "problem with sync"
Other one write to log - "Waiting for call ..." , and then write "Disconnecting"
Other one write to log -

"userxx logged in. xx.xx.xx.xx"
"l2tp_inxx: using encoding - MPPE128 stateless"
"userxx logged out. 1 110 669 9 11"
"l2tp_unxx: terminating..."
"l2tp_unxx: disconected"

Other one connect well.

Where is the problem ?!

We have related problems with pptp connections. After two or three days of using pptp by about 10 users the pptp server goes crazy. Only rebooting Router OS solves the problem
