Help needed regarding rules

hi all

im currently working on a project regarding ipfire setup and making policys. i have 1 vm on the green network and another on red. my issue is that im trying to create rules that allow the pc on red to accsess gui+ping green pc+SSH terminal. I understand that this ruins the firewall but its for a project and if this issue is fixed i will add another vm on red which will be marked as a ‘hacker’ and block and log pings etc.

are my rules correct?

is that even possible on ipfire because my lectrure recommended this firewall….
