A garden center client of mine just put in an environmental control system and I'm having a hard time getting it online. They need two ports forwarded, 1122, and 80. Their router is a Netgear WNR2000v3 with the latest firmware. I forwarded both ports and 1122 is working fine, however 80 is still blocked. I had their ISP open it; but its still showing as blocked. I can access the server via browser from inside the network with no problems. Access attempts from outside show up in the router's log, but there's no option for actual firewall settings other then forwarding. I added the server to the DMZ; but get the exact same result. Any ideas? Their ISP is Optonline, and from what I've read in the past they have pushed corrupt files to their docsis3 modems so that port 80 shows as open on their end; but is still actually closed. I'm at a standstill here, I figured that if port 80 is blocked nothing should show in the log. However if its a firewall issue,once I added the server to the DMZ, it should get a response. Any suggestions, or corrections to my thinking? Thanks
