Site to Site bridging server to client from local access server's client

[isisyodin]

Its almost a mouth full.

I have the following configuration:
client PCS<–-->(Local Access OpenVPN Server)-[SiteA]-(client)<–Site-to-Site--->(server)-[SiteB]- (Local Access OpenVPN server)<–-->client PCs

I want to be able to connect to SiteB openVPN Server and view SiteA's network. At the moment I can view SiteA network only while on the LAN of SiteB (or SiteA for that matter). Whenever I connect via VPN to SiteB from an external network, I don't have visibility of SiteA network.

I have tried adding SiteB IP VPN range in the IPv4 local network of SiteA client and SiteB server Site-to-Site connection. No go.
