A remote X connection is fundamentally the same as running the
following on you own host - both use TCP connections.

    xlogo -display 127.0.0.1:0.0 &

> If so how could I do this?

There are many methods - my preferred one is compressed,
encrypted, strongly authenticated and convenient, as follows.

    ssh -C -X 192.168.254.1 xlogo &

The following is a quick-and-dirty proof-of-concept; however, I
would recommend using the above method and running you Xserver
with the "-nolisten tcp" option.

    user at 192.168.1.1$ xhost +192.168.1.2

    user at 192.168.1.2$ xlogo -display 192.168.1.1:0.0 &

Yours sincerely,
