I want to restreint access to my ethereum node (geth) via rpc interface for some machines, for example : localhost and 10.x.x.x
how to deal with that?

It is a bad idea to expose your rpc server online, be carefull !!! – Badr Bellaj♦ Oct 2 '18 at 23:01
I suppose you want to restrict outbound as well as inbound connections.
There is parameter allow-ips for filtering outbound connections in parity, not sure about geth
--allow-ips FILTER Filter outbound connections.
It can help partially, but I think it would be better to do it on OS level.
- Windows - firewall.
- Linux - https://serverfault.com/questions/30026/whitelist-allowed-ips-in-out-using-iptables
- Azure VM - NAT
