This page documents how to configure IPv6 over a L2TP softwire, which is a method used by some ISP to provide IPv6 connectivity. It assumes Barrier Breaker (OpenWRT 14.07), but the old configuration for Attitude Adjustment (12.09) is available at the end of the page.
Offering support for both IPv4 and IPv6, IPSec is deployed when it comes to the implementation of a VPN. The terms "IPSec VPN" or "VPN over IPSec" refer to the process of creating connections via IPSec protocol. It is a common method for creating a virtual, encrypted link over the unsecured Internet. L2TP/IPsec¶ L2TP/IPsec is a common VPN type that wraps L2TP, an insecure tunneling protocol, inside a secure channel built using transport mode IPsec. L2TP/IPsec is supported starting with pfSense® software version 2.2-RELEASE. This article will explain how to configure the service and setup clients. To do so, enable netfilter connection tracking (conntrack) or manually load the Linux netfilter defrag modules at each tunnel endpoint. site-A:# modprobe nf_defrag_ipv4 site-B:# modprobe nf_defrag_ipv4 If L2TP is being used over IPv6, use the IPv6 defrag module. INTEROPERABILITY top Set the IPv4 Configuration Type to 'L2TP' Set the IPv6 Configuration Type to 'SLAAC' - you don't actually need a global IPv6 address on the interface at all - it will just use Link Local addressing, but setting to SLAAC seems to enable IPv6 on the interface without causing any problems; When you are finished, press Save at the bottom of the screen.

How to Set Up VPN on Synology with L2TP | KeepSolid VPN
Use the DNS and WINS Settings in the Mobile VPN Configuration. When you select the Assign these settings to mobile clients option, mobile clients use the DNS servers you specify in the Mobile VPN with L2TP configuration. For example, if you specify 10.0.2.53 as the DNS server, mobile clients use 10.0.2.53 as the DNS server.. When you select this option, mobile clients do not use the servers

The package xl2tpd must be installed to use this protocol. Turn off IPv6 on your Synology NAS . Before you enable the VPN connection, we recommend to turn off IPv6 on your Synology NAS. This will help you avoid IPv6 traffic leaks outside the VPN tunnel. To do this, follow the few simple steps below: Navigate to Control Panel > Network > Network Interface. Click on the LAN menu to expand it. L2TP/IPSec. L2TP (Layer 2 Tunneling Protocol) over IPSec provides virtual private networks with increased security and is supported by most clients (such as Windows, Mac, Linux, and mobile devices). For more information about L2TP, refer to here. IPv6-test.com is a free service that checks your IPv6 and IPv4 connectivity and speed. Diagnose connection problems, discover which address(es) you are currently using to browse the Internet, and what is your browser's protocol of choice when both v6 and v4 are available.
