Enabling remote users to access VPN CLient resources

[Phani]

I have set up VPN server and VPN Client for my Asus RT-AC66U_B1 router.

I have Network B connected to our network over VPN CLient on Router.

Everyone directly connected to the router can access the resources of Network B. But everyone that is connected to our network over VPN can't see resources of Network B. Any help much appreciated in this regard.

Thanks,
Phani.
