Site to Site VPN issue

INC_Techs — Fri, 03 Nov 2023 20:10:31 GMT

Hi,

We have 3 sites with Palo Alto PA-415 devices. Site A is the headquarters, and Site B and C need to connect with a site to site VPN to Site A. We have Site A and B connected, but site A and C won't connect. We setup the VPN connection the same way. How can we troubleshoot this? We have a ton of experience with Sophos firewalls, but these are our first Palo Alto ones, and not finding a lot of support online for this.

We decided to try the forums now.

Thank you for your time!

Every site has 1 or more ISP links?

Does phase 2 come up?

If you ping site A>C or C>A and check traffic logs is egress correct tunnel interface?
