the following works (& so does netatalk too)!

# ATALK #
#########
# allow AppleTalk/Netatalk to function as a server
-A input -i eth0 -p tcp -s 172.25.0.0/16 --dport afpovertcp -j ACCEPT
-A input -i eth0 -p ddp -s 172.25.0.0/16 -d 172.25.0.10     -j ACCEPT

As many of you suggested I will indeed learn iptables -- sometime (hopefully soon).

Thanks for everyone's your help.
