VPN Connectivity Errors

Hello,
I'm running server 2003 standard edition and I'm trying to setup VPN Access. I have several windows xp workstations locally and I can connect on the local network via VPN; however I can't from an outside network. I'm running an AD domain with DNS, DHCP and RRA (VPN) with one network adapter. I've setup users to be able to connect remotely. I 'm running a cable modem behind a linksys wireless router. I have a static address, gateway, subnet, and dns setup on the router from my ISP with port 1723 to forward to my server's local IP. I have DCHP on the router disabled and for testing purposes I've disabled my firewall and gone through some security policies on the server with no success. I keep getting error 678 no answer. I'm sure it's something simple that I'm overlooking.  Please help.

Thanks in advance

probably a FW somewhere blocking your ipsec traffic.

Is there a way I can test for that?

I would check 2 places first.
1 check your client side router and server side router, see if the ACL's are being used for your ports.
secondly I would check the server if it has any information on the connection.

Do you or someone you know control the FW at the server side? they could do a dump/snoop and tell you what they see.

I have access to the router on the server side but not the client's side at the moment. I currently don't have a program that can do a dump/snoop unless it's included with windows. I'm a little confused about ACL's, from what I can see on the server's side of the router the ports are open. For testing purposes to see if I had RRA setup properly I connected locally first without any issues and then disconnected before trying it from a workstation on another network.

Thanks

Looking at the server side router, do you see attempts , packet count increasing for the vpn in?

Looking at the router on the server side I found that logging was disabled, I have enabled it and I'm going to make another attempt to connect and see what the stats are.  It's a cheap WRT54G linksys router.

Hello Jim,
You where right it was a FW blocking the packets on the clients side router. I was able to connect after making some changes.  I'm going to re-enable the FW on my router with VPN passthough enabled and try the connection again. Thanks
