I have two computers, each one with two network interfaces, both are ubuntu. I want to implement bellow architecture:
I need to generate traffic from interface eth0:192.168.1.1 to interface 192.168.2.1 through firewall machine. How to implement this architecture?
by considering usage of iptables linux packet filtering in firewall machine to filter traffic.
another consideration: use of this architecture as a replicator of pcap files (client traffic on one interface and server traffic on another interface through firewall machine )
