Win2012 server to pfSense peer-to-peer can't ping far end

[jeff4bioeden]

Firewall is pfSense, 2.0.2-RELEASE (i386)

Trying to set up peer-to-peer, originating from a Windows2012 server
I can connect from the Windows server using a roadwarrior connection, so I believe all the programs are working correctly

LAN side config file, from the pfSense box:

dev ovpns3
dev-type tun
dev-node /dev/tun3
writepid /var/run/openvpn_server3.pid
#user nobody
#group nobody
script-security 3
daemon
keepalive 10 60
ping-timer-rem
persist-tun
persist-key
proto udp
cipher AES-128-CBC
up /usr/local/sbin/ovpn-linkup
down /usr/local/sbin/ovpn-linkdown
local x.x.x.x
ifconfig 192.168.10.1 192.168.10.2
lport 1196
management /var/etc/openvpn/server3.sock unix
max-clients 5
push "route 192.168.3.0 255.255.255.0"
secret /var/etc/openvpn/server3.secret
comp-lzo
passtos
push "route 192.168.4.0 255.255.255.0"

Config file from the Windows 2012 server (client) side:

dev tun
persist-tun
persist-key
cipher AES-128-CBC
resolv-retry infinite
remote x.x.x.x 1196 udp
ifconfig 192.168.10.2 192.168.10.1
secret auspeer.key
comp-lzo
verb 3

Connection establishes, but each end can ping only itself (pfsense box can ping 192.168.10.1, but not 192.168.10.2).  Windows client machine can ping 192.168.10.2, but not 192.168.10.1

Is it something obvious?
Is there any additional information that would be of assistance in helping me resolve?

Any assistance appreciated!

The OpenVPN config files look reasonable.
You do not mention firewall rules - what rules do you have to allow traffic into pfSense end OpenVPN? And same for Windows Server firewalling (however you do that using OpenVPN client on Windows Server).
