I don't suppose there is a tutorial out there that would show how to set up an IPSEC VPN? I saw the sticky, but it is from 2011 so it doesn't seem that relevant anymore. A pretty exhaustive search on google found a couple of tutorials that are also out of date. I am currently running PFsense 2.1.4-RELEASE.
Basically I am setting up a VPN so when my friends want/need to they can connect into my network. There are some network computers that I am giving access to. Also, some of the older games required Gamespy which is no longer around. So we have to LAN play to make things work. We are currently using Tunngle, but it is LOADED with ads and doesn't seem to work well.
Look a this one,
Following my actual setup and the basic setup you want to achieve (lan gaming), it should work fine.
Be aware of well understanding subnets and what "using a different subnet" for mobile clients means"
If you'r using the default 192.168.0.1 configuration and the subnet mask is 255.255.255.0, using 192.168.4.1 IS NOT A VALID DIFFERENT SUBNET.
you can have a look at my actual personnal config in this post: https://forum.pfsense.org/index.php?topic=83781.0
my second post show print screens of a "partially working" config (you will understand if you read it all).
