How to use three nodes in OpenWrt

Please help:

I do not know how to realize three mobiles using three nodes in a Router which have three SSR nodes each. eg:
In this router , it has Russian SSR nodes, Janpanese nodes, Austrilian nodes, mobile1 want to use Russian SSR nodes, mobile2 want to use Janpanese nodes, mobile3 want to use Austrilian nodes.
Please help me, Thanks sincerely!

I don’t think this will work as you’d need multiple SSR instances and this isn’t (I think) possible.

You can, however, set a command line shortcut to change the node as often as you like but for specific devices it may not be possible.

You can have 2 VLANs one with SSR nodes and one without and two separate Wi-fi networks.
