Challenge setting up remote access to computers using a DrayTek Vigor Router

Hi Everyone,

I have a bit of experience with setting up Netgear Routers, in particular setting up remote access to a group of client computers (connected to a Netgear Router) using TightVNC.

I am currently attempting to setup a DrayTek Vigor 2760 router for remote access, but am having considerable difficulty.

As best I can tell it is a three phase process with this router -

1). Setup a Service "Object" describing the custom VNC service, e.g.:

Object Settings > Service Type...



2). Setup an Address "Object" -



The above dialog only offers "Range", "Sub-Net" and "MAC" as options, and I have tried both the "Range" and "MAC" address options (however neither has been successful).

3). Setup a Filter Rule -



Now when I attempt to connect to the remote computer using TightVNC I see the following error screen -



As a side note I have also turned off the Windows Firewall on the client computer (which I am attempting to connect to).

If anybody can offer any help here it will be greatly appreciated.

Kind Regards,

Davo

have you verified you can connect to the target from the internal LAN?

just to make sure you have the host machine setup correctly.

Hi Hugo,

Thanks for your interest. I have a TeamViewer session running to the computer which I am trying to setup, and from that (remote) computer I am connected to the router (which is a remote router with regard to my physical location).

TightVNC gives me a couple of advantages to TeamViewer, 1). It is free, even for commerical use, 2). I can connect to remote computers - provided that they are turned on - with no need to get remote staff involved (e.g.: to startup TeamViewer).

Any additional advice will be appreciated.

Kind Regards,

Davo

So the answer is No,

You would need to TeamView into a different PC in the building and from that remote PC try to VNC into the desiered destination.
this will tell you a few things.

If it works then the problem exists in the router and you have confirmed the PC is working as it should, as far as software & firewall settings
If it does not work then the PC is causing the issue and you need to sort that out before looking at the router.

BTW you can set TeamViewer to autostart with windows so no user envolvement is required.

Hi Hugo,

I can confidently skip this step as it was not until recently - when the remote office changed routers - that these issues started. The issue is 100% with the router.

Also TeamViewer still isn't free for commercial use, so I will not be using it beyond the trial period.

Kind Regards,

Davo

I would still give it a test, I can't count the amount of times windows updates has renabled the firewall / deleted custom rules.

regardless, try a different port, try it to a different LAN IP or different PC. Do you have any other rules passed through the firewall (either working or not working)

Have you tried open port on Vigor 2760?

Please go to "Network" --> " NAT" --> select type : open port and fill ing mapped IP address
