Let pFSense act as an IPSec XAuth VPN Client
Since it seems impossible for two PC in the LAN network to connect as Road Warriors to a remote VPN IPSec server, it would be useful to let PFSense act as a VPN client itself and let it share the dialup VPN connection to a remote server.
As far as I have seen, it should be supported by strongSwan (https://www.cisco.com/c/en/us/support/docs/network-management/remote-access/117257-config-ios-vpn-strongswan-00.html), just it is needed to configure it through the pfSense GUI.
The two missing information for this kind of VPN connections are the XAuth Identity and password, plus the different parameters, like authby=xauthpsk, leftauth2=xauth and so on.
I create this issue in Redmine just as proposal for future versions.
