Could you also attach AVC msg which you are getting? Did you submit it with this report?

SELinux is preventing /usr/sbin/xl2tpd from read access on the file nm-xl2tpd.conf.2172.

*****  Plugin catchall (100. confidence) suggests  ***************************

If вы считаете, что xl2tpd следует разрешить доступ read к nm-xl2tpd.conf.2172 file по умолчанию.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
чтобы разрешить доступ, выполните:
# grep xl2tpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Установил selinux-policy-3.11.1-74.fc18, но не работает.

1) SELinux is preventing /usr/libexec/nm-l2tp-service from name_bind access on the udp_socket .
2) SELinux is preventing /usr/sbin/pppd from read access on the file nm-ppp-options.xl2tpd.6974.
3) SELinux is preventing /usr/libexec/nm-l2tp-service from using the signal access on a process.
4) SELinux is preventing /usr/libexec/nm-l2tp-service from using the sigkill access on a process.
