Site to site and a red

Question

I have an environment with two sites running XG210 (SFOS 15.01.0) . One of the sites has a RED connected to it. We will call it site A. Site B is able to talk to site A just fine. The issue is when site B tries to communicate to the RED that is connected to Site A. They are not able to. I have tried added the remote network on the Red. From site B i have added a policy for source and destination. Do any of you out there have this setup?

The RED link is now working as expected for me, without needing to add any additional routes. Long story short, I think this issue was related to the fact that on my XG firewall I had two physical ports configured with IP addresses in the same range (don't ask). This resulted in some other issues, and in the process of troubleshooting some other changes I was making, I discovered that traffic was routing both directions as expected through the RED link. While I can only note correlation, I suspect that the IP assignments on the XG were the cause of my issue. Unfortunately, it is tough to revert the changes to prove causation because I believe I had the XG in a state that should not be allowed, and was causing other weird issues.
