I'm beating my head. I have this working perfectly at one site, and it won't work at another.
Site has a new external vendor coming in. Vendor has installed a router on the internal network going to 172.16.207.187/32 (on the other end). Internal interface of said router is 10.16.135.4/24. Internal interface of ASA (router of last resort on network) is 10.16.135.1/24. I have added a static route on the ASA to point any traffic destined for 172.16.207.187/32 to 10.16.135.4. The ASA is dropping the packet. Packet tracer is stating the packet matches the implicit deny rule.
ASA 5512-X and is v9.0.3. I have another site with an ASA 5505 v9.0.3 and this works PERFECTLY without any config change.
I have tried adding ACLs from the internal network to the remote IP and the ASA never matches the traffic.
