We have some web sites hosted with a third-party company, and wish to use web deploy. They have told us that we need to ensure that port 8172 is open, as that is needed. As a test, they gave us a URL that uses that port, and said to try using telnet to connect.
We have tried using telnet, but it sites there for a while doing nothing, then reports "Connect to host lost". If we enter our IP address and this port number into http://www.yougetsignal.com/tools/open-ports/ it confirms that the port is closed.
The set up here is simple, the PCs are connected to a Netgear N600 router, which plugs into the wall. Our ISP says they don't block any ports, so it seems to be either the PCs or the router. I had a look at the router web page, but couldn't see anything that indicated it blocked ports. However, Netgear's web site says their routers don't block any outgoing traffic by default, so the fact that it can't telnet out might rule out the router being the problem (but I could be way wrong here).
I looked through Windows Firewall, but couldn't see anything obvious (not that I really understand what I'm looking at). Following some instructions I found here, I turned on firewall logging for the Domain, Private and Public profiles, and tried to telnet again. The log showed a few entries like this...
2017-05-11 16:30:20 DROP ICMP 192.168.1.1 192.168.1.22 - - 160 - - - - 5 1 - RECEIVE
...and then lots like this...
2017-05-11 20:02:28 DROP UDP 192.168.1.11 220.127.116.11 5353 5353 381 - - - - - - - RECEIVE 2017-05-11 20:02:28 DROP UDP 192.168.1.11 18.104.22.168 5353 5353 381 - - - - - - - RECEIVE 2017-05-11 20:02:28 DROP UDP fe80::5265:f3ff:fe01:7d10 ff02::fb 5353 5353 401 - - - - - - - RECEIVE
I don't see any reference to that port number in there, so I'm not sure this tells me anything.
Anyone able to help me? I need to open that port so I can telnet out. Please let me know if there is any more info I should give.
UPDATE - I'm now not sure this is the problem at all. Whilst trying to see if I could connect to the URL at all, I came across this post, which suggested trying to use telnet to connect to gmail.google.com on port 443. Given that this port is (presumably) open on my machine, as I can use secure sites, this should work. However, I got the same problem as before, namely a few minutes pause, then the message "Connection to host lost." Anyone any idea what's going on here?
