There is something weird happening with the debug output, NetworkManager isn't iterating through the NetworkManager-L2TP VPN settings and only showing data : ((GHashTable*) 0x1e764c0) (s)
instead of the name/value pairs.
Anyway, looks like the VPN server isn't responding, possibly because it doesn't like the phase 1 and 2 proposals the client is offering.
Could you obtain the ike-scan.sh
script from the following page:
and then try the following but replace 123.54.76.9 with the VPN server you are using :
sudo yum install ike-scan
sudo ipsec stop
chmod a+rx ./ike-scan.sh
sudo ./ike-scan.sh 123.54.76.9 | grep SA=
I copy paste code to ./ike-scan.sh by instructions from link.
Than run sudo ipsec stop
command.
(I think is not necessary, but) Replace ip to 123.54.76.9. https://ibb.co/cGQ25J
output:

Sorry I didn't realise CentOS / EPEL7 didn't include the ike-scan
package, but it is great that you built it.
Looks like CentOS 7.5 has upgraded libreswan
package to version 3.23 and you are now impacted by the weak legacy algorithms issue :
[The output of the ./ike-scan.sh
script has the same output repeated 7 times which doesn't look right as they should be unique. But if all of proposals advertised by the VPN server contain SHA1
(i.e. the output of the ./ike-scan.sh
script), then they are consider weak by libreswan-3.23.]
The best fix is to re-configure the VPN server and add proposals that use SHA2
, but if you aren't able to do that, in the IPsec Options dialog box advanced options, add the following:
I made a guess what the phase 2 algorithms should be as they are often based on the phase 1, but some VPN administrators decide to use completely different algorithms from phase 1.

I'm not sure what could be wrong with libreswan
as it is not giving useful errors, so could you try strongswan
instead, it might give better hints.
To use strongswan, issue:
sudo rpm -e --nodeps libreswan
sudo yum install strongswan
You'll then need to change the phase 1 slightly for strongswan (by replacing ;
with a -
) :
Forgot to mention if libreswan and strongswan are both installed at the same time, then NetworkManager-l2tp will use libreswan. That's why libreswan needed to be removed with sudo rpm -e --nodeps libreswan
for NetworkManager-l2tp to use strongswan.
sudo rpm -e --nodeps libreswan
yum install strongswan

I've setup a CentOS VPN to try and reproduce the issue, but ran into a few issues.
SELinux was preventing strongswan from running properly :
Jun 14 21:34:26 localhost.localdomain python[2895]: SELinux is preventing /usr/libexec/strongswan/starter from getattr access on the file /run/nm-l2tp-ipsec-c359dcd6-d0abb-4ed6-becd-a0ba393ed5fb.con
I then tried to disable SELinux by editing /etc/selinux/config
, but SELinux is still running after a reboot.
Sorry i'm still sorting things out, so might not have any suggestions for you till tomorrow.
Maybe useful info about my machine:

Sorry for the delay in responding, I've been away. There is something wrong with CentOS 7.5's strongswan, I'm not able to establish a connection even with SELinux disabled.
Could you delete the Phase 1 and 2 Algorithms and downgrade to an older version of libreswan. To downgrade to an older version of libreswan, you can do :
sudo killall -TERM nm-l2tp-service
wget http://vault.centos.org/7.3.1611/os/x86_64/Packages/libreswan-3.15-8.el7.x86_64.rpm
sudo rpm -Uvh --oldpackage libreswan-3.15-8.el7.x86_64.rpm
Then try the connection again.
No problem :)
After downgraded something new appears, but not connected successful.

So looks like the IPsec connection is now successful, but the L2TP connection is failing.
The reason the IPsec connection failed previously with the newer libreswan is because the Phase 1 and 2 algorithms were wrong. The output of your latest log with the old libreswan has :
... ISAKMP SA established {auth=PRESHARED_KEY cipher=aes_256 integ=md5 group=MODP1024}
I then ran the ./ike-scan
script to confirm and i see:
sudo ./ike-scan.sh 88.119.193.209 | grep SA=
SA=(Enc=3DES Hash=SHA1 Auth=PSK Group=2:modp1024 LifeType=Seconds LifeDuration(4)=0x00007080)
SA=(Enc=AES Hash=SHA1 Auth=PSK Group=2:modp1024 KeyLength=192 LifeType=Seconds LifeDuration(4)=0x00007080)
SA=(Enc=AES Hash=MD5 Auth=PSK Group=2:modp1024 KeyLength=256 LifeType=Seconds LifeDuration(4)=0x00007080)
In the ./ike-scan.sh
output, aes256-md5;modp1024 is the the strongest phase 1 proposal offered and that's why the old libreswan chose it.
Which means the following phase 1 (and most likely following phase 2) can be specified with newer libreswan versions :
The reason the xl2tpd L2TP connection is failing is most likely due to a PPP issue and you should be able to find the reason in the system journal output, i.e. issue :
journalctl -b
It would be pppd that is generating the output.
journalctl -b output:

Was that sudo journalctl -b
output after running the following and trying the VPN connection ?
sudo killall -TERM nm-l2tp-service
sudo /usr/libexec/nm-l2tp-service --debug
If so, it's odd that we don't see any pppd output. Which would also means xl2tpd is failing before it starts its pppd child process, but it is not giving any useful output error message.
Yes sudo journalctl -b
output was after running the following and trying the VPN connection.
I will be adding support for rp-l2tp
as an optional alternative to xl2tpd
maybe in the next few weeks as rp-l2tp
sometimes works when xl2tpd
fails for some weird reason.
Sorry I wasn't of much help with the xl2tpd
issue.
Thanks of help. Finally I connected.
To resolve xl2tpd
issue for me help this article:
https://linuxexplore.com/how-tos/l2tp-vpn-using-xl2tpd/
I tried connect to VPN but get this:
