OpenVPN Multiple Site-to-Sites routing problem!

2bad4u

I'm trying to setup a Peer to Peer ( SSL /TLS) as this:

Site A : Server multi wan and LAN = 10.0.0.0/23
Site B : static ip and LAN = 10.0.2.0/24
Site C : static ip and LAN = 10.0.3.0/24

Tunnel Network = 10.1.1.0/24

I have created WAN rules for the port 44441 and OPENVPN on all sites.

OpenVPN Server Config Site A:

dev ovpns3

dev-type tun
dev-node /dev/tun3

CSO Site A config for Site B:
Common name = pfsense01
Tunnel Network = 10.1.1.0/24
IPv4 Remote Network/s = 10.0.2.0/24

CSO Site A config for Site C:
Common name = pfsense02
Tunnel Network = 10.1.1.0/24
IPv4 Remote Network/s = 10.0.3.0/24

OpenVPN Client Config Site B:

dev ovpnc1

OpenVPN Client Config Site C:

key /var/etc/openvpn/client2.key
tls-auth /var/etc/openvpn/client2.tls-auth 1
comp-lzo yes
resolv-retry infinite

This is where i get stuck;

Site A can ping Site B and Site B can ping Site A

Site A cannot ping Site C and Site C can ping Site A

Site B cannot ping Site C and Site C cannot ping Site B

There are no connection problems from TLS or certificate.

Could you please help me.
Thanking you in advance and looking forward for your reply.
