I can’t seem to get a VPN working. My test setup is OPNsense connected to WAN configured with DynDNS dynamic address. I am attempting to connect to the OPNsense VPN using an iPad (iOS 10) over 3G network. This setup works well to test VPN (PPTP, L2TP, IPsec) on firewalls e.g. monowall or Sophos. This pathway has no demonstrated VPN connectivity problems and the WAN IP address is correct.
I have tried three VPN setups (PP2P, L2TP, IPsec) on OPNsense without success:
PPTP: installed plugin, configured PPTP settings listening on WAN, created PPTP user, and setup PPTP firewall rules (screenshot attached). When I try to connect with the iPad: “The PPTP-VPN server did not respond”. The most recent entries in the PPTP log file:
Apr 6 09:07:32 pptps: PPTP: waiting for connection on 192.168.1.1 1723
Apr 6 09:07:32 pptps: process 11772 started, version 5.8 (root@sensey64 21:52 27-Mar-2017)
L2TP: installed plugin, configured L2TP settings listening on WAN, created L2TP user, and setup L2TP firewall rules (screenshot attached). The iPad does not connect. The L2TP log file:
Apr 5 21:12:18 l2tps: L2TP: waiting for connection on 192.168.1.1 1701
Apr 5 21:12:18 l2tps: process 86558 started, version 5.8 (root@sensey64 21:52 27-Mar-2017)
IPsec: Setup tunnel and mobile client. Screenshot attached. I did notice on the Phase 1 proposal, there is not a place for Peer Identifier, which is called Group Name on the iPad VPN client. I left this empty when setting up the iPad settings. I created a system level group named “VPN Users” and a user with VPN: IPsec XAUTH dialin privileges. Firewall rules were created. The IPsec log is as follows:

Any suggestions on getting any of these interfaces to work?

Any reason not to use OpenVPN? It's more secure than pptp and by far the easiest to configure
