Hi @Descat, Dominique (Nokia - FR/Paris-Saclay)
One of networking options here for your scenario -- Create 2 different subnets --Subnet 1 (calling it DEV) for AVM1 and Subnet2 (calling it PROD) for AVM2 . Then all subnets 's Route Table to have entry for SRV server. A lot of control can be made from route tables of subnets. Single user id can be used.
