I created a L2L tunnel between Corp and ME. When I am on corp side asa I can ping the inside interface of the other side and tunnel comes up. From inside the corp side I can not get any pings to respond from the ME side except the asa inside Ip address.
From the ME side ASA Fw I can ping inside the corp to a few devices and get a response fine. It appears that for some reason the tunnel is only allowing traffic one way. From Corp to ME but not from ME to Corp. Sh cry ipsec sa shows it incrementing when I ping from ME, but not from Corp. The tunnel also will not come up if I try and initiate it from the ME side.
Not sure why... any ideas? Here are the configs of both sides.
