Remote users using the VPN client 3.5 experience unexpected disconnection from time to time. When this happens they can reconnect but cant seem to be able to connect to any internal server.
Checking the Pix 520 in debug the problem would appear to be the following:
ISAMKP (0): DPD: received seq_no 256740580 != expected seq_no 256740575
return status is IKMP_NO_ERR_NO_TRANS
This continues to appear if the remote user disconnects and then reconnects, and doesn't seem to right itself until the connection has fully timed out at the PIX end.
Is there anything I can do to
1) Stop this problem from happening in the first place, or
2) Reset the sequence numbers in some way to minimise the problem when it does happen.
Thanks
