Two LAN subnets need access both directions

[juke]

I have 2 networks - pfsense network 172.16.20.0/24 and Lab network 172.16.40.0/24.

I can ping each server, ping to the internet, and ping systems on the 172.16.20.0/24 network from both servers on the 172.16.40.0/24 network. But I cannot do the same the other direction. I would like to be able to have the same access either direction!!! Any help would be great!

I am using the default gateway and dns for both networks.

pfsense IP - 172.16.20.1 - DHCP Enabled on that network

I have LAN fw rules added:

IPv4 * 172.16.40.0/24 * * * * none    
IPv4 * LAN net * * * * none   Default allow LAN to any rule 
IPv6 * LAN net * * * * none   Default allow LAN IPv6 to any rule 
IPv4 TCP LAN address * 172.16.40.0/24 * * none

Added a route:

172.16.40.0/24 WAN_DHCP - 172.16.10.1 WAN LAN 2 WAN Route

And a manual outbound NAT rule:

WAN  172.16.40.0/24 * * * WAN address * NO

Thanks,
Josh
