IPsec VPN between Cisco ASA 5505 8.2(5) and MikroTik 6.40.5

Hi All, I’m trying to set up IPsec VPN between Cisco ASA 5505 8.2(5) and MikroTik 6.40.5. The whole configuration looks good for me, but it isn’t working properly. I can ping MikroTik’s inside IP address (10.10.10.1/24) from computer connected to ASA’s inside network (10.46.32.0/24), but only that IP. When I’m trying to ping any other device in MikroTik’s inside network I’m getting time outs. From MikroTik’s inside network to ASA’s inside network there is allways a time out. Gateway (10.99.99.254/24) for outside network (10.99.99.0/24) doesn’t exists.

Could anyone look at this configuration files? I don’t know where I’m making a mistake. If it’s not possible to set up IPsec tunnel with that software version on ASA, please let me know.

Please try disabling the FastTrack firewall filter rule, see if it resolves the issue. If it does, you need to accept IPsec traffic before the FastTrack rule.

After disabling the FastTrack firewall rule, It’s still the same behavior.
