Hi Guys,

I've browsed the boards before asking this and have asked the question on softether webstite, and although a lot of people had similar issues to myself, I couldn't quite find a response for the same issue I have. Although I am very tech savvy I am very new to VPN so I apologise for any ignorance in this field.

I have a readynas 104 set up in a property next door. It is connected to a virgin superhub via ethernet and it is accessible on the internal network just by using SMB or AFP.

What I am trying to do is access this same NAS drive from the property next door without the need to run a huge cable between the houses.

The readynas came with the softether bundle addon included, so I have installed this addon and the server software installed correctly.

I then downloaded the server manager onto the PC and began setting it up. The setup I went for was an L2TP/IPSec setup as outlined in https://www.softether.org/4-docs/2-howt ... VPN_Server and I followed this article closely.

Now in order to make any modifications to this server via the server manager, I have to enter the external IP address 82.XX.XX.XX. The VPN appears to be running, I have added a user account to connect to, and there appears to be no errors from the server manager.

Where I really get the issue, is when trying to connect to the readynas through VPN externally.  

I am looking to connect my mac to the VPN so used the instructions as outlined in https://www.softether.org/4-docs/2-howt ... ient_Setup

The computer seems to think about it, then rejects the connection on the grounds that the VPN server (readynas) was not responding. The software on the readynas VPN is working correctly, because if I enable a local bridge I am able to connect to the VPN via the internal IP address 192.168.0.3 (which the readynas is located on).

All my attempts to connect externally to the readynas seem to have been problematic. I have disabled the router firewall and opened ports 1701, 500 and 4500 as I have read somewhere that they need to be open.

Am I missing something obvious here? This is advertised as an easy setup, and although I can't say the instructions were difficult, I am having not much success.

Any help would be greatly appreciated.

PS. I can use the server manager to connect to the external IP address, however this only works when I remain on that network. As soon as I go to the other property, the settings entered in server manager, no longer connect.
