We moved offices but kept the same ISP. Our IPs changed of course. The new IP info is:
IPs: x.x.x.10-14 Mask: 255.255.255.248 (/29) Gateway: x.x.x.9
(seems weird that it's not 8, but ISP insists, and we do have internet access. Also, I tried plugging the server directly into a spare port on the modem, and assigning it the .11 IP and route and ip addr won't even allow me to use .9 for the gw)
Router is using .10 as WAN IP by the way.
I'm using basically the same NAT Alias (1:1 NAT) entry in our Syswan router that I was using at the old location just with the different WAN IP.
Local LAN IP: 192.168.1.220 Traffic Direction: Inbound WAN IP: x.x.x.11 WAN & LAN Port Range 80 ~ 80 Protocol: All WAN: WAN 1
Maybe I'm forgetting something in Apache or the Network config of the server? From inside the LAN I can browse to the site with the local or wan IP or dns name of the server. From outside, it times out.
Site is wordpress running on Apache2 in /srv/http port 80. I don't think I should need to change anything here.
