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 (192.158.2.197) 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?

Thanks.

Hi Denise,

 

Thanks for helping. The link you shared is the same as mine in the beginning of post. I have followed the instruction for port forwarding. Do you have other techniques?

 

Thanks.

@jasonleakey I am having the exact same issue as you, also running BGW210-700, with firmware 2.5.6. I was researching it and ran across your post. Did you happen to find a resolution with this hardware?

I'm running a webserver on my home network, and when accessing it from the home network, sometimes it seems okay, but often I'll experience slow page loads and timeouts. Accessing the webserver from outside is blazingly fast.

After endless investigation into what I thought was a generic issue with port forwarding, I believe the actual problem is that NAT loopback is flaky on the BWG210-700, at least as of 1.7.17:

NAT loopback is a feature which enables a machine on your local network to access resources via your public IP address as if you were connecting from the public internet. This explains why you are only seeing issues on your local network.
