Connecting to a Netware 6.5 SP8 server through a firewall

I have set up a firewall between one LAN and one WAN (Perimeter network). Two of the windows systems on the WAN need to connect to a Novell 6.5 SP8 File Server on the LAN and one Novell 6.5 SP8 server on the WAN needs to be accessable to systems on the LAN.

Everything on the firewall works except these last two conditions. My research is telling me that it is because the Novell servers are using IPX protocol and for some reason it looks like my RouterBoard CCR1009-8G-1S-1S+ firewall is set to block IPX traffic by default.

Can someone help me configure the firewall to allow IPX Traffic through the forward chain?

Thanks!
