I have one out of 10 L2TP/ipsec clients configured the same identical way to connect to same server , not able to encrypt when /ppp profile is set to use-encryption=required
All other clients have not any problem
Only this one gets an active connection if “use-encryption=yes” is set: this way, the field “encoding” is displayed blank in SERVER ppp active connections while the correct encoding is shown in CLIENT l2tp interface status…
Any idea please ?
This is log when encryption fails :
