I am trying to open port 80 and 3690 for HTTP and svnserve respectively (inbound for both). I have Windows Firewall off, and have tried temporarily disabling Mcafee VirusScan Enterprise, to no avail. According to http://www.yougetsignal.com/tools/open-ports/, both ports 80 and 3690 are still blocked. I can't think of what would be blocking them if Windows Firewall and my antivirus are disabled. Here is the output of netsh firewall show state
Firewall status:
-------------------------------------------------------------------
Profile = Standard
Operational mode = Disable
Exception mode = Enable
Multicast/broadcast response mode = Enable
Notification mode = Enable
Group policy version = Windows Firewall
Remote admin mode = Disable
Ports currently open on all network interfaces:
Port Protocol Version Program
-------------------------------------------------------------------
3690 TCP Any (null)
22 TCP Any (null)
80 TCP Any (null)
1900 UDP Any (null)
2869 TCP Any (null)
Any help? I'm not sure what each item on the list of enabled/disabled items is, but "Operational Mode" is disabled, so I assume that one refers to me disabling Windows Firewall. I know that since Windows Firewall is off, this output might not be useful, but I figured I'd include it just in case, haha.
I ran nmap on our global IP and here is the port information it gave:
Host is up (0.00031s latency).
Not shown: 988 closed ports
PORT STATE SERVICE
135/tcp open msrpc
445/tcp open microsoft-ds
554/tcp open rtsp
2869/tcp open unknown
3390/tcp open unknown
5357/tcp open unknown
10243/tcp open unknown
49152/tcp open unknown
49153/tcp open unknown
49154/tcp open unknown
49156/tcp open unknown
49175/tcp open unknown
I'm not sure how it retrieves this information, so I don't know how to change it on the machine.
First of all make sure that no services are using those ports. try
netstat -aon
and find PID of services running and then goto task manager enable PID column and check whether any service is already using it. – Renju Chandran chingath – 2014-07-13T06:23:05.2201Does your ISP allow connections to those ports? Do you have a router performing NAT, which you would need to configure port forwarding on? – Bob – 2012-06-07T16:42:40.517
From what I've found online, my ISP does not block port 80, and I'm not sure of 3690 (although, I'm trying to fix this 80 issue, at the moment). This computer is the server for the house (internet is shared to the router from our desktop, and DHCP is handled on the desktop also). I haven't enabled port forwarding yet, I'm just trying to get the desktop to open the port first. – Caleb1994 – 2012-06-07T16:48:31.333
If you haven't configured port forwarding, then an external port checking tool is not going to work. You could set up a webserver or something and just try connecting within your local network. Also, that site has never worked for me; the PF Port Checker is more reliable (the downloaded program is listening on that port at the time of testing).
– Bob – 2012-06-07T16:50:57.720I also checked it with canyouseeme.org, and it showed closed also. I'm not at a Windows box, now, so I can't use PF Port Checker. Also, I checked with nmap. I'll update my post with the results from nmap. I enabled port forwarding, and forwarded HTTP to my room (where I already had apache2 running on Kubuntu), and still no luck. – Caleb1994 – 2012-06-07T17:57:40.360
Could our router still be blocking the port, even it is only functioning to route traffic? E.g. DHCP is disabled, and it simply takes packets from the main machine and passes them around the network. It doesn't have to do NAT. Our desktop machine does all of that. I hope not... it was trying to take things over when we set it up, so we set it up on a different subnet, and it would be a pain to get to the routers settings... (I don't remember the IP or the subnet...) – Caleb1994 – 2012-06-07T18:56:36.143
