Hi.
I have a firewall ASA5516-X and have this issue that i don't know if it could be accomplished.
I have read in a blog that this can't be done, but first I would like to ask here.
I have 2 firewalled networks.
Over PORT1 I have a network that has a Windows Server 2016 Domain Controller with its DNS.
Over PORT2 I have another firewalled network with different range.
I have created an Access Rule in between the 2 subnetwork in which I permit all the traffic for all of these ports
https://support.microsoft.com/en-us/help/179442/how-to-configure-a-firewall-for-domains-and-trusts
and a NAT .
- I can ping from 10.10.10.20 to 10.10.10.10
- I modified on PC 10.10.10.20 the file windows\drivers\hosts a line to say that TESTING.COM = 10.10.10.10
so I can ping TESTING.COM
But when I try to add PC to the domain TESTING.COM it fails.
"An existing connection was forcibly closed by the remote host."
(error code 0x00002746 WSAECONNRESET)

Many thanks
