how to viewing VPN Parameters on Google Cloud - Phase 1 and Phase ?

[jotaemec41]

Hey everyone!

I've got a classic VPN set up on Google Cloud, and it's been working great. But now I've got a burning question: How can I check out my VPN's parameters? Specifically, I'd like to take a peek at the Phase 1 and Phase 2 settings. The four parameters I'm interested in are:

1. Diffie Hellman
2. Hashing
3. Encryption Type
4. Lifetime

If anyone has a clue on how to access this info or if there's some magic command I can use in Google Cloud to uncover these secrets, please spill the beans! I really appreciate any help you can offer. Thanks in advance!

Hi,

Not sure how to check these values using terminal or cloud shell, haven't tried this one. But the details or the values or the ciphers that you are looking at are this link[1]. These ciphers cannot be modified.

The link shows all of the supported ciphers in IKE. The one thing you need to remember is that when you configure your on-prem VPN, make sure that the ciphers you use are supported from the IKE cloud VPN. Once configured properly, it will automatically work.
