We have just converted the APs in our medical school to LWAPP. The med school is the only group here that uses the native Windows L2TP/IPSec VPN client.
Now they are experiencing frequent VPN disconnects, so much so that it is unusable. What I see in the VPN logs is:
Session closed on tunnel 10.250.59.190 (peer 1,
local 15427, serial 0), reason: Call disconnected for administrative reasons
Any idea what is causing this or how to fix it? The clients do not appear to be dropped from the AP when this happens, although that is somewhat difficult to tell as the client association report only shows associations; not dis-associations...
