Ok, here's my situation, mind you i'm extremely new to Cisco router/firewalls. I have a internal device that generates a vpn tunnel to a remote location. However I have a ASA 5510 as my firewall. How do I configure the ASA 5510 to allow the VPN traffic through the firewall. I have opened up the UDP, ESP, GRE ports and am allowing pinging. However I am unable to establish a connection to my remote location. I am also unable to ping to any outside location. I have checked the internal and extrenal devices and they are configured appropriately. So my issue has to be with the firewall.
If I have posted this in the wrong location please let me know the appropriate spot.
