HELP! - VPN and port forwarding

post #1 of 14
Thread Starter 
Hello,

Been a bit absent from overclock.net for a while but my lack of networking knowledge has led me back here again.

I basically am after a knowledgeable fellow user to answer a few potentially noobish questions I have around networking, topics in particular are...

VPN's - I pay for HMA VPN Pro and have read guides about building your own VPN at home but does this give me that same thing....

Port forwarding - why can't I get this to work!? And when I do it is only on certain ports.

I can ask questions here or in PM. Just a friendly helping hand when I get stuck - which I am now haha!

Thanks

Will

Please edit your topic title to something more appropriate.

I don't understand your question about VPN's.

And exactly what issues do you have with port forwarding?

VPN is a virtual private network, you need a end point of some sort, so at the mmoment you are using HMA 's endpoint. Yes uyou could get your own to do the same, but you would need a server to act as a gateway

Its probley a firewall issue, its really simple when u think about it these are the common things off the top of my head
1) is the service running?
2) is the servicing listing?
3) can people on your lan see it? (use nmap from anoter machine)
4) have you forwarded the port to the right ip?

I think the title is appropriate. It is networking advice that is needed and it might not extend completely to just VPN's and port forwarding.

Thanks for the reply. The benefit of having HMA installed as a client is that I can connect to various servers, locally and internationally. Presumably having an end point on a home pc (such as a NAS or HTPC that is always on) will provide an ip address that is the same (regionally) as a computer on the same network. So in terms of anonymity, this gains nothing but will provide a secure connection when connecting away from home such as in a cafe wifi environment?

I have OpenWRT installed on my router (TP-Link WR1043ND) and have redirected (forwarded) the ports used by a particular program but when I check using an online service, they are not listed as open.

What I am not sure about is how to test that they are fully open properly?

Firewall is configured to allow those ports for the program.

How can I test 1,2 and 3 in your list?

My PC using the program has a static IP and this is correct.

Thanks for help.

1) Can you see it in task manager smile.gif?
2 and 3) grab a copy of nmap from http://nmap.org/,

Install it on the pc you are trying toforward to and scan the port you are trying to open, if this works install it on another pc do the same (scan the pc your trying to forward too), can you see it? If yes its not a local firewall

then its something in your router smile.gif

Thanks, we are now reaching the limit of my limited knowledge!

1) The program is listed in task manager as a process but not a service
2) I installed nmap on my pc and entered in the target the PC's IP address only - is this correct? It scanned all ports - none are open, the state is lited as unknown for all of them. This is the case with HMA VPN running as well as not running. I asked HMA if installing HMA vpn has any effect on port forwards to which they replied no but I am not convinced..
3) not tested yet

Thanks for bearing with me!smile.gif

Sorry when i say service i just mean something that gives something, if its in task manger its running smile.gif

If you enter the command (replace with the relavent info

nmap -p

It only scans the relavent port smile.gif (it only scans top 1000 ports as standrd should have said!)

When HMA vpn is running it wont create something listing, it connects out stuff dosnt connect in. It dosnt have any effect on port forwards tongue.gif, i thought you were trying to port forward another thing? (IE a server of some sort)

As an example of an out put I should get, is this correct, I put my ip in target and nmap -p 22 so command was nmap -p 22 192.168.1.xxx

PORT STATE SERVICE

22/tcp unknown ssh


Port 22 should be open (or at least I would like it to be) to SSH into my router.

I am trying to forward a port for a another thing, a server.

Does your router have a ssh server installed and listing?

Try adding -sX to the scan to see if that says differnt, if you know its open (can connect on local host) then its a firewall issue

What I mean by your title not being appropriate is because it doesn't really explain what you want to have help with. It's in the networking section - of course you want networking advice. Even a thread title like "Confused about VPN, and port forwarding" would be acceptable.
