I have a TP-Link 150M router that is our gateway.
If I forward port 3389 to .128 I can remote into .128. CanYouSeeMe.org shows 3389 open.
If I disable this entry then CanYouSeeMe.org reports 3389 as closed and I cannot remote into it.
I am looking to forward port 80, 3011 and 1911 to an A/C controller. The A/C people state that they cannot hit their controller.
CanYouSeeMe.org shows 80, 3011 and 1911 as closed. I thought that perhaps this was due to a configuration on their controller. So I set up IIS on a spare server and http:\\localhost
(from that spare server) brings up the iis7 page. I then forwarded port 80 to that new server and CanYouSeeMe.org still shows 80 closed.
Any idea as to what is going on? I need to open 80, 3011 and 1911. ISP doesn't block anything.
