Network tab missing from Parallels Desktop 17.1.0, and thus I can't set up port forwarding

I'm running Parallels Desktop 17.1.0 which I bought yesterday on an x86 mac with Big Sur 11.6. I want to set up port forwarding to a linux VM, but [this page](https://download.parallels.com/desktop/v13/docs/en_US/Parallels Desktop User's Guide/33341.htm) says that's done via the Network tab in the preferences, but as you can see in the attached, I don't have any such tab. (This is a newer UI view which shows the network tab too: https://download.parallels.com/desktop/v17/docs/en.lproj/43109.htm)

 

The image didn't seem to work , so here's a different copy
