I'm going to preface this by stating that I am a total newbie when it comes to Cisco products.
I was tasked with setting up our new Cisco ASA 5506-x for use as a network firewall and to connect via VPN into our office.
I managed my way through the initial setup and was able to connect via the VPN etc... The beginning of this week, I was tasked with setting up to authenticate vs our Windows 2012 R2 AD. I got that going. Then with setting up 2-factor authorization. That's working as well. On to the problem at hand...
When I setup the VPN NAT rules, I decided to use split tunneling so that user Internet queries would go through their own connections. I managed to make that work. Yesterday, my boss came to me and said that he wanted to go from the split tunnel to having everything tunnel through the VPN connection. I assumed that this would be relatively simple. And I have managed to NOT be able to figure out how to change over from split tunnel to hairpinning. I can see how it's supposed to be, but I keep missing something. I'm assuming this is a problem with my NAT rules. I'm posting a sanitized version of the running-config. (I just restored to this a few minutes ago so that I can still VPN into the office as I have been.)
Please, if anyone has any insights into this, it would be exceedingly helpful.
Thank you,
~Robert~
