Limiting user access to the network card, is that possible ?

Hi !

First, the setup:

LINUX 2.2.16 box connected to Inet and Private network

eth0   = Inet
eth0:0 = Private Net (IP Aliasing)

Users ssh from Internet on the box to do their business

Second, the requirement:

Restrict the access to the eth0:0 (internal network) to the selected group of
users, so that only those who where choosen can access internal network from the

And finaly the question :) Is that possible at all ? There are no /dev/ethxx,
ipchains does not support user/group level accounting (AFAIK). If that is not
possible, what will be the best walkaround ?

1. full networking for console user, limited networking for remotely logged in user


I need to setup a lab. such that the users logged on to console have
full access of lan and internet but, users remotely logging(via
telnet/ssh) into the lab servers would be allowed only to access lan(
i.e. others servers in lab only) and would not be granted access to
network outside of lab, i.e. to internet.
I would use RedHat 9.0.

So how to go about doing this ???
