WZR-HP-G450H Port Forwarding
« on: December 11, 2012, 07:02:50 pm »

I have a WZR-HP-G450H running DD-WRT v24SP2-MULTI (09/27/12) std - build 20025. Almost everything is working correctly, other than the following strange behaviour, which I've isolated to something relating to fort forwarding. I have serveral static IPs set up, with some ports forwarded to each. When everyhting is configred and I restart the router, the router picks up an IP from the modem, but there is no connectivity bwteen WAN and LAN. If I disable the port forwards and restart the router, I have connectivity. The forwards can then be re-enables and applied. I'm not really sure if they're working at this  point, but that's a separate problem. Any idea what I can do to get the router working so that it can be re-started with the port forwars in place, or what I may be doing wrong?

I think I have the identical issue, but with a WZR-HP-AG300H.  I have a couple of machines with statically assigned IP addresses on my network.  I then add some simple port forwarding rules to the AG300H router, and then restart it.  The router seems to connect to my ISP, and gets a WAN IP address, but none of my machines can access the internet until I disable the port forward entries.

My problem turned out to be caused by a typo in the source IP box.  I was trying to only allow incoming connections from a certain subnet, and I had specified that incorrectly.  Changing it to xxx.xxx.xxx.0/24 fixed this issue for me.  Perhaps bad data in one or more port forwarding fields can result in broken routing to the WAN when applied during dd-wrt bootup?
