Port forwarding SLOW for internal requests
I have an ARRIS BGW210-700 at home and setup Port Forwarding for my home web server. The port forwarding works normally for external requests, but not for internal requests.
Use case 1:
I want to visit the home web server (220.127.116.11) from internal IP (192.168.2.150). I confirm visiting by IP works well. But when I visit the server using domain name, it doesn't. It's slow or timeout, Chrome shows 'Connecting...'.
Use Case 2:
I forwarded the port to my own laptop (192.168.2.150). Same results. Slow or timeout.
I used to be a Fios customer, and had no problem with a same setup on their Fios-G1100 gateway. But not in this ARRIS gateway.
Could you help me troubleshoot this problem?
