I setup a L2TP VPN server on my Raspberry PI. When I tried to connect to it from my iPhone, I got the following error in the /var/log/auth.log file:
Jan 3 10:53:08 raspberrypi pluto[4116]: ERROR: asynchronous network error report on eth0 (sport=4500) for message to 172.56.31.191 port 46424, complainant 172.56.31.191: Connection refused [errno 111, origin ICMP type 3 code 3 (not authenticated)]
What does this mean, and how can I fix this issue?
Someone had a similar question on the openswan mailing list several years ago. Good luck; I found setting up L2TP w/ IPSec much harder than openvpn.

– Hydraxan14 – 2017-01-03T23:29:26.210strongswan
version for Raspbian 8 is 5.2.1.pluto
was removed in 5.0.0, andcharon
handles IKEv1 now. You might want to set up a newer version of strongswan before proceeding.I never setup strongswan I am using openswan. Should i use strongswan instead? Is there a big difference in the configurations? – Ahmed Soliman – 2017-01-03T23:30:41.347
