Cisco VPN 3005 Concentrator - configuration tips?

we have a problem to configure a cisco 3005 for vpn access. the vpn is in parrallel to the firewall, so the problems shoulodn't be from there. I have connected the external interface directly to the internet (via cable and a cisco 2500) the private interface directly to the lan. I can ping and admin the vpn device from inside and outside. I have used the sample configuration from ciscos website to establish a vpn connection over PPTP with internal user and PAP authetification without encryption. Any variations in routingtables and/or clientadress managment doesn't change anything. As client I used a w2k worstation with lan access to the internet and get the folloeing error on w2K:

"error 619: to the given port no connection is established."

the vpn event log says:

**********************************************************

second client is a macintosh using NTS TunnelBuilder Clientsoftware for VPNs (PPTP and L2TP). The errormessages on the vpn are similar (no additional info...). On the mac the error is: LCP: VPN Server is not responding to configure request. First it seems that the tunnel is established (TCP and PPTP requests are negotiated the the server drops the connection).

Anyone out there any ideas where I can seek the failure or where I can get further information about configuring?

Thanks Andreas
