Hi, wondering if anyone has some pointers on this which would be great.
Basically i have a cisco 1601 with no ACL's running nat.
On the NAT statment i have:
ip nat inside source static tcp 192.168.0.229 1723 209.213.71.50 1723 extendable
ip nat inside source static udp 192.168.0.229 1723 209.213.71.50 1723 extendable
when i try connecting to 192.168.0.229 from the inside on the LAN it works fine. when i try remotly from outside the cisco router i get as far has verifying username and password then after a minute i get error 721. which is a GRE error, with that said i have no ACL's for GRE packets should be allowed.
What am i doing wrong, is it the router im using, too old, although i cant see this being the case if everything is opened.
heres what i see in the windows log:
A connection between the VPN server and the VPN client xxx.xxx.xxx.xxx has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47). Verify that the firewalls and routers between your VPN server and the Internet allow GRE packets. Make sure the firewalls and routers on the user's network are also configured to allow GRE packets. If the problem persists, have the user contact the Internet service provider (ISP) to determine whether the ISP might be blocking GRE packets.
