I've been trying to configure a network as follows:
I've got four computers connected as follows:
Host1: has one network card - eth1 with ip 192.168.1.2. It is connected to eth1 of Host2 via vlan1
Host2: has two network cards. eth1 has ip 192.168.1.1 and is connected to eth1 of Host1 via a vlan1. eth2 has ip 192.168.2.1 and is connected to eth2 of Host3 via vlan2
Host3: has two network cards.
I am facing problem connecting 3 network through my linux firewall/router box.
Scenarios is like this,
eth0 --- External (Internet)
eth1 --- Internal (Internet access to local clients) -- 192.168.1.0/24
eth2 --- A separate Network with access from eth1 on a particular port -- 192.168.10.0/24
The setup is working perfectly using iptables for eth0 and eth1.
