Lately we have seen some VPN issues with L2TP.

SSL and PPTP still work, though we don't use PPTP, only for testing.

L2TP, fails with username/password error, same details used in working SSL connections.

We've reset the shared secret but makes no change, anyone have any ideas or seen similar?

Syslog shows as chaps error:- [L2TP][L2L][1:Quantum][@*.*.*.*] CHAP resp: authentication fail   2024-08-05 15:42:42 L2TP (VPN-20, test@test.com) ==> Protocol:CHAP(c223) Failure Identifier:0x01 E=691 R=1 C=627133C0FC860FE7B83EF3D7A46677D7 V=0 M=Good luck! ##
