Hello. I have a problem with a Cisco 2800 Router. I can't connect from the inside network to outside using a GRE VPN client (MS). I did a packet capture and responses are coming on the outside interface but they never reach the inside interface. I allowed both IP protocol 47 and TCP 1723. I've attached the running config. Please help.
It doesn't work with the acl only, but the method described in the link above with the inspection policy did the trick. Thanks.
