Hello List,
i have a linux box with 3 interfaces.
- Internet
- 2nd Company Network
- Internal Network
Physically it looks like this:
--------------------------------
ppp0 (Internet), eth0 (plugged into DSL Modem)
eth1 (External-Network, 10.10.10.1/24)
eth2 (Internal-Network, 10.10.10.2/24)
I thought of setting up a bridge with eth1 and eth2, which would "merge"
the two networks together and i would get br0.
Now I have the problem that I still want to firewall eth1 and eth2!
E.g. I only want to allow traffic going to 10.10.10.100-200 (on serveral
ports) to leave interface eth1.
Can someone point me to the right place for more infos or examples?
Thanks, Mario
