I just upgraded from 1.2.3 to 2.0-RC3 and it's rocking!. However, I'm having issues with port forwarding. It's working ok from outside, but on internal side… if I enter internal IP address such as 192.168.0.1:9091 it'll work but if i tried it with domain name like domain.com:9091 it'll failed to connect. Never been a problem with 1.2.3 and I noticed there's new feature called port reflection and I'm wondering if that have anything to do with this or do I need to setup custom DNS to create loopback for domain to 192.168.0.1?
This might help you :)
Thanks for the link, and found Split-DNS as solution to my problem.
