Have troubles with connecting to my VPN from Mac. Using default Mac client, pre-shared secret. Also this works well on iOS 10.3.2 from the same Wi-Fi network.
Firewall is disable, no Little Snitch. macOS error message says 'The L2TP-VPN server did not respond'
Also, I've tried to connect open free VPN, us.freel2tpvpn.com and got no response again, so I think it's a macOS problem, not the server / routing.
Do you have any ideas?
Here is my /var/log/ppp.log

update 1 checked udp ports 500, 1701, 4500 — all open from mac
update 2 set up another l2tp ipsec preshered secret server on windows and got same result — don't respond on mac, connected on iphone
update 3 wiresharked booth on 'connections', and there is no udp packets from mac on connection, but test packets are ok.
definitely the mac vpn client is broken (firewall is off), where should I dig?
