One Direction site to site vpn
fid500
I am trying to setup a one direction ipsec site to site VPN between A and B sites. The traffic will be originating from site A to site B. I am trying to limit traffic from Site A to only HTTP and allow only return traffic from site B. site B should not be able to initiate any connections.
I have a problem getting the tunnled up when I add a group policy on the ASA at site A. If I use the default grouppolicy it works fine. Can someone tell me what I am doing wrong. Where should I apply the ACL to control ports and hosts going through VPN?
Thanks
