Routing All Traffic Through e-VPN
First, you will need to disable all unused WAN interfaces. If you don’t do this then you won’t be able to check the “Change default route to this VPN tunnel ( Only single WAN supports this )” option. Granted you can probably create a manual static route anyway but that’s not ideal.
Click General Setup under the WAN menu then disable all unused WAN links.
Next click on LAN to LAN under the VPN and Remote Access menu. Assuming you have no profiles already set-up then just click the first one. You can see that I already have one (currently offline)
Now it’s time to configure the main options. I will briefly go through the options below.
For profile name, you can call it whatever you like. I called mine e-VPN London.
VPN dial-out via WAN1 – for you, it may not be WAN1 so make sure you select the right one (check the first screenshot of this article). Netbios and multicast are unlikely to be used so block these so you don’t send unnecessary traffic over the tunnel. Call direction is self-explanatory.
Always on makes the VPN tunnel ‘permanent’ otherwise it’ll timeout after a default inactivity period of 5 minutes. If you want to manually establish the VPN tunnel then you should uncheck this box.
Under dial-out settings, the username and password will be your email address and VPN password.
The type of server you are calling is L2TP with IPsec Policy = Must. This is the most secure and recommended method.
The server you are connecting to is one of your choice – e.g. unitedkingdom.e-vpn.co.uk
The pre-shared key is securevpn
From the first subnet to remote network, you have to do NAT.
Change the default route to this VPN tunnel ( Only single WAN support this ) you want to check this box to make all traffic go via the VPN.
Click Ok, wait for a few minutes and then check if the tunnel is active.
