One user has VPN client 3.9, NWclient 4.91,
We have BM 3.8 sp3, on Netware 6.5 sp3

When he is using NMAS he is thrown of with this message:
"Failed recieving server DH public value"

Our authgw.nlm is 6.01.19

When using "Backward Compatibility" he stays on...
We have had his PC on an other ADSL line (with another router) and there is
no problem - he stays on for more than 24 hours, with NMAS.
