FVS336Gv3 - L2TP/IPsec on Windows 10

I have a Windows Server running RRAS with PPTP. The FVS forwards this with no problem. 

The problem is we now need to move to L2TP. I have created this on the Windows server, and from within the LAN, a client machine (my laptop) can connect directly to the server(using the internal server name). But as soon as I go outside the network it doesn't work (using external address). 

 

 

We do have a site to site IP SEC VPN running between this FVS and one in another site. I hope this isn't causing the problem??

 

I have forwarded UDP 500, 4500, 1701 and pretty much every other port in desperation. I have enabled L2TP Passthrough. I have made sure the external address is pingable. I have upgraded the firmware today to 4.3.4-1.

 

Any suggestions greatfully welcome!

 

thanks,

Arron

    Thanks, but the server is connected via the LAN port. It's the FVS that it is the the modem's DMZ.

      Thanks for the response Dane

       

      I would prefer to use the VPN server I already have on my Windows server. 

       

      Having said that, I have already been through this as a test and following that guide I did manage to establish an L2TP connection to the FVS, no traffic went through, and I couldn't ping or connect to anything. 

       

      The setup is: 

       

      [Windows Server]---Lan---[FVS336Gv3]---[FIBRE MODEM]---[WWW]

       

      The Fibre modem and the FVS both have public static IP addresses, and the FVS is in the DMZ of the modem. 

       

      thanks,

        Hi Arronj,

         

        Welcome to the community!

        You should connect your Windows Server to FVS336Gv3 LAN port ,not DMZ port. FVS336Gv3 only supports access LAN by L2TP from WAN side.

         

        Thanks
