Hello,

 

I currently trying to set up a VPN connection to a computer within out office that is hosting files we'd like out field engineers to be able to access.

 

The problem is we are in a shared office building (Regus) and so have a dynamic IP address and not NAT settings access to set tup port forwarding.

 

Any body any idea of any softeare out the that would allow me to achieve this with the current setup.

 

The computer in the office is running Windows 7 but i was thinking about installaling Windows Server which may provide me with more options.

 

Thanks

 

John

Does this machine have a public IP address?  Or is it a 192.168.x.x or 10.x.x.x address?

 

Perhaps a solution like Dropbox might be a way to have field engineers able to access.  Not sure how much data we're talking about.

Hi RKilroy,

 

 

Sorry for the delay.

 

The server is sitting on a private network but within a shared office building the first local IP is 192.*** the second 10.**** (the private regus network) and the third hop is the public facing static ip address.

 

We currently use Dropbox but it is not big enough for our requirments.

 

John

This is outside my area of expertise, but I think that you would have a heck of a time getting this set up over two private IP address networks.  You might want to consider going to a business or enterprise plan with a cloud based provider.  Here are a few examples Sharefile, Dropbox, OneDrive, formally Skydrive, or Google Drive

The only way you can allow a connection into your comptuer is if you have access to the router/switches that face the public internet (to forward ports/Vlans/IP's) to your computer sharing the files. Or contact the owner of the building and tell them you need a public IP address for a server. The other option Is what RKilroy posted.

The other thing you could try is asking if the server/PC you need to connect to can a) have a static private IP address, which it should have anyway B) be put in the DMZ. This would necessitate more security on it but would then be outside the router(s) firewall(s)


Hope this helps thumbup.gif

Is the dynamic ip assigned to the computer or the public address? If the out side address does not change You can still setup a IPSEC Vpn tunnel.
