I have to connect to a VPN L2TP/Ipsec
Under Ubuntu 18.04, I used:
IPsec Tunnel to L2TP Server - yes
Phase1 = 3des-sha1-modp1024!
Phase2 = 3des-sha1!
Force UDP encapsulation
I have installed Ubuntu 22.04 now, the VPN connects, but I cannot access the internet or the protected websites.
The colleague working on the server suggested me to try
Phase1: aes256-sha1-modp2048,3des-sha1-modp2048
Phase2: aes256-sha1,3des-sha1
I already tried some options from this page and didn't helped:
22.04 l2tp client not working
- downgrade xl2tpd to 1.13.12
- kl2tpd instead of xl2tpd
- libreswan instead of strongswan
Can anyone help me taking a look at the output from
journalctl -b --no-hostname _SYSTEMD_UNIT=NetworkManager.service + SYSLOG_IDENTIFIER=pppd ?
