Cant reach WAN gateway from OpenVPN clients.

[jvelez88]

I have a multisite to site OpenVPN setup, the 3 of them have multiple WANs, from SITE A LAN 1 and 2 I can reach clients in SITE B and SITE C LANs, from SITE B LAN I can reach clients in SITE A LAN 1 and 2, and SITE C LAN and from SITE C LAN I can reach clients in SITE A LAN 1 and 2, and SITE B LAN, but I cant reach WAN side GATEWAYS IPs of any side from any of the LAN clients.

Recently I changed SITE A WANs to a VLAN setup (all the gateways are in the same interface but different VLANS, this because an 8port smart switch is waaaay cheaper than a multi port ETH PCI card) and before this change I was able to reach gateways from any LAN I tried. I dont know if this setup is not possible or if I missed something. The funny thing is that I cant even reach gateways on site B or C that are on a dedicated interfaces.

In resume:

All LAN and VPN clients can reach each other.
All LAN clients can reach GATEWAYS attached directly to their PFSENSE routers.
None VPN clients can reach any gateway.
None LAN clients can reach GATEWAYS attached to PFSENSE routers on the other sites.

I need to reach every network from every client and I dont know whats wrong in my configuration, any one may shed some light on this issue?
