If all three systems have wireless connections to that router, then they
should be able to communicate.

Again with Shorewall cleared on both systems, in one system type 'ip
addr ls'.

That will show you the IP address of your system. It will look something
like:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UP qlen 1000
    link/ether 08:00:27:7c:20:d2 brd ff:ff:ff:ff:ff:ff
    inet 10.0.2.15/24 brd 10.0.2.255 scope global eth0
    inet6 fe80::a00:27ff:fe7c:20d2/64 scope link
       valid_lft forever preferred_lft forever

In that example, the IP address is 10.0.2.15.

Now at a shell prompt on the other system, type 'ping <address of first
system>' (e.g., ping 10.0.2.15).
