Phase 2 tunnel status

L2 Linker
 

Please excuse me as I am still learning and am relatively inexperienced. I assume the phase 2 status can be red for following reasons (assuming IKE phase 1 is all correct and working) Authentication, Encryption, DH settings being incorrect/mismatched or lifetime expiring. Are there any other reasons it would be red perhaps to do with remote or local LANs or IPs and could you explain in layman terms?

Hello,

You are correct that you can have a good phase 1 and a bad phase 2. Most of the time its a configuration mismatch, could be passphrase.

Hope that helps.

Also if local and remote proxy ids does not match that can also cause phase 2 shown as red.

Hi @pink-panther 

 

I would disagree with @OtakarKlier. If pre-shared key is wrong phase1 will not be completed. If phase1 is established, this means the pre-shared key (alongwith the rest of phase1 settings) is the same on both ends.

 

And would agree with @MP18 - most common reason for failing phase2 is local and remote proxy id (encryption domains). But similar to phase1 it could also fail due to Authentication, Encryption or DH settings

@Astardzhiev  Is there an authentication in Phase2? I thought auth piece only happens in the phase1 of the negotiation.
