Hello. Let me first explain our problem and a brief explanation of our setup, and then I will go into details.
We currently have a Cisco Firepower 2110 and are using this for a site-to-site VPN to our other building. There are no issues here. We are attempting to set up a RA VPN, and when testing - by allowing inside interface as access - we can connect internally. The problem is we can not connect externally.
I did have a Cisco ASA 5500 series before, and we did have a S2S and RA VPN functional on it.
What is odd, is if I allow a trusted external IP any/any access, it connects, but it routes to our core router login screen which is 192.168.x.1 (depends on vlan).
