Answers:
There is none.
From what you are clich¨¦ adjectives the machines hold 2 cards. This is a deeply poor instrument to run the system and reduce your control. They should adjectives enjoy solitary one card, and use this for both types of access (lan and internet). You can catch routers beside filter, so you can block confident machines by address. Alternatively run them through a Linux firewalling server to the internet and control their access from this.
