[NEBULA] Route between Port Group 1 and Port Group 2

Good morning,

i have a simple question but i can't found a solution.

This is my scenario:

WAN1 -> Public IP (Internet)

Port Group 1 (Lan1) -> 192.168.10.1

Port Group 2 (Lan3) -> 192.168.62.228 static, dhcp disabled

I'm in a migration scenario, my old lan is 192.168.62.X with a switch and all the old assigned computer. The new lan 192.168.10.1 is the new one, have correctly access to internet and all work well.

I need that the computer in the new lan (192.168.10.x) can reach computer in the old lan (192.168.62.x), in nebula, how can configure that?

Thank you!!
