Replicating PPTP VPN Functionality

[tuaris]

This isn't a post complaining about the removal of PPTP.

I had to replace t1n1wall with a new device that uses OPNsense.  The PPTP VPN which was available in t1n1wall allowed me to easily setup the VPN server to provide access to all the networks, including IPSec tunnels, and WAN/Internet that were configured on it.  This was very useful in that I could VPN into my home network and access the Internet as if I was home, and access all my remote offices without having to do any additional setup on my part.

I'm having trouble replicating this behavior with IPSec mobile VPN (https://docs.opnsense.org/manual/how-tos/ipsec-rw.html#vpn-compatibility).  I can barely access my home network, let alone any remote offices.  I haven't even begun to think about "remote" Internet access. I'd prefer not to use OpenVPN since it requires installing extra stuff on the client side.

Are there any instructions on how to do this?
