Your missing the AVC report? SELinux is preventing /usr/libexec/nm-l2tp-service from name_bind access on the udp_socket .
***** Plugin catchall (100. confidence) suggests ***************************
If вы считаете, что nm-l2tp-service следует разрешить доступ name_bind к udp_socket по умолчанию.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
Do
чтобы разрешить доступ, выполните:
# grep nm-l2tp-service /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

***** Plugin catchall (100. confidence) suggests ***************************
If you believe that nm-l2tp-service should be allowed name_bind access on the udp_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep nm-l2tp-service /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Ok, could you try to execute # chcon -t l2tpd_exec_t `which nm-l2tp-service` and re-test it. Thank you. # chcon -t l2tpd_exec_t /usr/libexec/nm-l2tp-service (not in the PATH so which does not work) With that label, l2tp connects just fine - is this a packaging bug with NM-l2tp or something that should be fixed in selinux-policy ? Great, thank you for testing.
