Hi,

We have discovered following problem

The remote network (offices) have a NT server and an IPsec enabled router. The
router encapsulates the TCP/IP packets into IPsec packets.  When using the
default tcpip MTU ( = 1500), on the NT server,  we get problems when doing file
transfers. When we lower the tcpip MTU to 1444 we don't have these problems.
The remote office ISP is a different one then our ISP.

Does anyone had similar experiences ?

regards,
Guy
