Vpn client gets disconnected from concentrator with RST

When I try to connect to the concentrator with any software client, the cleint gets disconnected. When I use the 4.0.3. client the log shows the following output:

433 09:46:27.657 12/23/03 Sev=Info/6 IPSEC/0x6370001F

Retransmitting last packet!

If I use Ipsec/udp I also do not get a connection.

Can anyone please help me and tell me what could be wrong?

Re: Vpn client gets disconnected from concentrator with RST

It seems that this has to do with the user authentication: if I set the Authentication field in the Ipsec tab to None, the client authenticates (without the need to fill in a user/pwd), if I put it back to Internal, The client gets a "Remote peer no longer responding" message when trying to connect.

Does anybody know what could be wrong and why Internal authentication goes wrong even though there are users in that group?
