Hi all,
Here my problem I need connect to server on 2000 port its actually manageSIEVE port. Connection setup goes fine SYN->ACK SYN->ACK. When server send me first packet Router thinks its skinny fragmented packet. This packet goes into internal queue and not forwarded of course (wait for other packets I suppose).
In attachment you can find log enabled:
debug ip nat detail
debug ip nat fragments
I don't have command ip nat service skinny - its cisco851 box and yeah I've tried on another box this command doesn't help anyway.

Hi Nikilay,
the support contract comes by category depending on the type of equipment, an adsl router is like Cat. 1 or 3, I can check that tomorrow in the office.
