I am trying to establish a GER / IPSec VPN connection between two routers. One the VPN end is behind a ASA firewall. I would like to allow the GRE / IPSec VPN packets through the firewall.
i have allowed the following following ports through firewall.
access-list inbound extended permit esp any any
access-list inbound extended permit udp any any eq isakmp
access-list inbound extended permit udp any any eq 4500
access-group inbound in interface outside
I have also tried sysopt connection permit-ipsec
But nothing worked for me. Any suggestions...?
I am aware that this topic has been discussed serveral times. But since, none of them really helped me, i am opening this topic.
