Billion UK Forum

Let me start by saying what I'm trying to do and then I'll explain how I think I should be doing it.

I have an office network which sits behind a 7800DX router firmware 2.32d. I want to be able to connect to that network securely from around the world from an individual laptop runngin Windows 8.1 so it appears as though I am local to that network.

I have read and researched but the manual for the 7800DX and the actual setup pages are somewhat different and all the previous posts in the forum seem to be wanting to set up more complex situations.

This is what I have done so far:

• Established a VPN account with username and password with TUNNEL enabled and a connection type of REMOTE ACCESS
• Enabled an L2TP Server using "Default or IPSEC", an authentication type of CHAP. I have chosen a Peer IP address in the DHCP subnet of the BIllion's DHCP server but one that would not be assigned by the server. Tunnel authentication and everything else is turned off
• In the IPSEC section I have created a connection using my main WAN interface and IPv4. The remote secure gateway is blank as I have ticked ANONYMOUS. I have entered a PSK

As far as I can see from previous posts, this is all I need to do on the Billion

From my Windows 8.1 laptop (on a different network), I have created a VPN connection.

• The address of the VPN connection is the WAN IP address of the router (pingable and reachable).
• Under security I have selected an L2TP over IPSEC protocol with the PSK entered under Advanced Settings
• Authenticating using CHAP

When I try to connect I enter the username and password entered in the VPN Account section but I get an error 789 saying that "the security layer encountered a processing error during initial negotiations". The Billion log from the connection attempt is attached.

Any help in getting me connected would be hugely appreciated. I'm not lazy, I have tried to figure it out but I just can't.

try following the attached guide

Thank you. That was a great help. I am now connected.

However, I can't notice a difference! I have a local IP address but I still don't appear to be "on" the remote network from my laptop. Actually that's not quote correct, I can "ping" local computers (brilliant!) but I can't access them. For some reason Windows seems to think I am on a "public" connection and so won't give me access to private resources. I can see I'm not now in the realms of Biollion problems but general Windows issues, but any help you can shed would be appreciated.

Have you tried to access them using \\192.168.1.x for example, screen shot example shown, once you can access it, you should be able to map the drive

No, that's not working for me

Just tested it from here, using a win 8.1 machine to a windows 7 machine and everything works fine (see attached screen shot)

As you can ping the devices it can't be a billion issue
