Hi All, I have one unit of Windows Server 2008 R2 installed on vmware with Routing and Remote Access installed. The server is configured using 1 NIC, and having an public IP point to this NIC IP Address. Protocol Used: PPTP AD: Yes Perimeter Firewall: WatchGuard X500 Routing: Disabled 1) Test internal to access the VPN, working - Means connection from the internal network to the internal IP of the VPN server is working and client can connect. 2) Try to connect to the VPN over public network using public ip, have authentication error (Error 619) - Cannot authenticate the users for the vpn connection using the public IP from public network. What Have Been Done Ping of public IP points to the VPN server Port 1723 and GRE Opened from the firewall Need some assistance to resolve authentication/connection to the VPN server from public network. Cheers, Emmanuel

Hi Emmanuel, Thanks for posting here. If we could successfully established tunnel form internal then I belive the firewall or the router might cause this issue . So is this RRAS having an valid internet address and connect to internet directly , isnt it ? Do we have set NAT on X500 ? RRAS(VM)----Firewall------Internet We have a similar issue before which caused by some vendor router devices , so could we check that first? A PPTP Client might fail to connect to a VPN Server on the Internet through an ISA Server 2006 http://blogs.technet.com/b/isablog/archive/2009/01/07/a-pptp-client-might-fail-to-connect-to-a-vpn-server-on-the-internet-through-an-isa-server-2006.aspx Thanks.
