routing traffic between two network cards through firewall
- by RubyFreak
I'm trying to test a network device (firewall) using a Linux box, with two network cards, one interface connected to the WAN zone and another interface to LAN zone.
The configuration is similar with that
|ETH0| <-> | FW | <-> ETH1
So from both interfaces I'm able to ping the respective firewall interface. But i'm not able to fire something like:
ping -I eth0 ip.from.eth1
and to get any answer. Is that possible or should the linux network namespace solution or user level tcp stacks (VMs are out of question)
