Hi everybody,
I have an issue configuring the CISCO ASA 5512-x (IOS 8.6).
The IPsec tunnel is successfully created between ASA and another non-CISCO router (hereinafter "Router"). I can send ping packets from Router to ASA, but ASA is NOT able to reply to those requests. Sending requests from ASA is also NOT possible.
I'm trying to interconnect to LANs 192.168.2.0/24 (CISCO, interface DMZ) and 192.168.3.0/24 (Router).
The CISCO ASA has a static public IP. The Router has a dynamic IP so I'm using dynamic-map option...
Here is the "show run" output:

Don't you have any idea what do I have wrong? Probably some wrong NAT/ACL I guess, but I could always find something only for 8.4 iOS and not 8.6... Maybe and probably I already messed the configuration with unwanted commands, but I was trying various things...
Please, if you have any idea, let me know! Thanks a lot!
