Help pushing GRE through Cisco 871 firewall
Posted on 2008-06-12
Hi i'm having an issue with my Cisco 871.
We have a PPTP VPN server on our LAN and i need to be able to push connectivity to it through the Cisco firewall.
Pushing port 1723 works but i can not figure out how to push GRE 47 through the firewall through SDM.
right now i am a this point with the firewall on, the vpn client attempts to connect to the server, hte server registers the connection but it never finished connecting and the client gets timed out
if i turn off the firewall i can establish the connection no problems.
Can anyone offer some assistance?
