SSL VPN from Site A to Site B via RED

Hello,

I have two sites (Site A and Site B) that are connected via RED. "RED # 5
Both sites have connectivity and can reach each other's network.

My problem is that my SSL VPN (for Site A) can access resources on Site A, but cannot access anything on Site B.

Site A

Network 192.168.0.0
SSl Network 10.81.234.0

Site B

Network 192.168.40.0
SSl Network 10.81.237.0

Within the Vpn SSl Settings, I left the following access

Allowed network resources (IPv4)
RED # 5

Is it a firewall problem and am I simply setting the wrong rules? Or is this something with the VPN configuration itself?

Thank you.
