We have setup a new BM3.8 VPN Client-Site server but are not able to
connect using Backwards compatibility mode or NMAS (NDS Mode). When
connecting with Backward compatibility mode we are getting the following
error "Authentication gateway failed to verify entered parameters. Format
error reported by the authentication gateway". We have used VPNCFG to
generate the encryption information that is needed for backward
compatibility but it still doesn't work.
NMAS (NDS) mode gives the following error when connecting "Failed
receiving server DH public value. VPN has not been authorized for this
user or method." For testing purposes we have created rules that allow
everything (users, protocols, methods) but that also does not resolve
this issue. The BM documentation is very poor and we are out of ideas.

Any help is much appreciated,
