Thanks for your help Karl.

Really only one of the five remotes sites is lossing the connection.
Al the sites are identical (hardware and software).

The ciped-cb in the remote continues running when the error msg appears in
the central site.
No error messages in the remote site.

I verified during the weekend (no activity in the remote site) and I had no
The first errors began on monday morning. Traffic related ?

I suspect a link problem, but I'm not sure, since in the same times, that I
lose the connection, the link becomes very very slow (ping 3 sec versus
normal 50 msec)

But, the link runs OK if I'm not using the cipe VPN.

May the link have some restrictions to UDP packets ?

Let me point that this site has a different link that the others.
It has a point to point digital line (64 K) and the others microwave links
of higher speeds.

I will thanks any advice to try to solve this problem.

I will try this option, but I think that there is some particular issue with
this remote site.

Many thanks in advance
