I am having a strange problem with client connections to our BM server.

I can connect okay and get given an IP address. But then very quickly in
some cases I am unable to ping any hosts on the site subnet. If I
disconnect and connect again then it connects okay but the same can happen
again. If it start a ping to a server as soon as the client connects then
it stays alive okay.

Is this a known error related to others posts?

Is there a setting to set a keep alive that I can check?

BM 3.8 SP4
Client 3.8.9
