WOL different ip classes

[Dark000]

Fog server is on ip (xxx.x.92.xxx). I successfuly send wol package to computer on the same ip class (92).

Like this:

I love it that you cand send it directly like this.

My problem is with computers on different ip class (xxx.x.93.xxx). Is that even possible. If so, what changes and modifications do I need to make.

If I remember rightly, and I guess google/bing here is a good tool to use, I think udp port 7 needs opening between networks?
