I could not set Priority and Severity for this bug, but I would like to set both to "High".
Can you try the 4.16.0 kernel https://koji.fedoraproject.org/koji/buildinfo?buildID=1064627 I swear I saw a regression/fix related to L2TP but I can't find it in my e-mail
I could resolve the L2TP connection issues by installing xl2tpd-1.3.8-7.fc27.x86_64 from testing repository update with kernel 4.15.14-300.
Thanks for letting us know. Feel free to reopen if the bug shows up again.
