VPN l2tp+ipsec: not work with last kernel 4.11.3-200

[Dario Lesca]

Yesterday I have update my fedora 25 and after reboot VPN l2tp+ipsec do
not work anymore.

The connection happens without problem, the routing are set correctly,
the DNS (UDP protocol) and ping (ICMP protocol) to remote host work.

Only the access to some server, like ssh or smb:// (TCP protocol) do
not work, in this case, if I monitoring on remote server with tcpdump,
none arrives.

If I reboot with previous kernel (4.10.17) all work fine.

Some suggest?

Many thanks

Do you use dnsmasq? I had the same issue until I set dns=dnsmasq in
NetworkManager.conf. I don't remember exactly why it's needed, found
somewhere at GitHub.

No, I do not use dnsmasq.
Resolve remote name using remote DNS work (UDP) and also ping to remote
IP work (ICMP)
