Quick network question

[kyle lanson <kylelanson@xxxxxxxxx>]

Hello,

A bit off topic, but I'm just wondering if there's anything in the kernel that might help me on this problem.

I need to construct a scenario where I can exercise my firewall rules without having a separate client machine. Assume my only network interface is eth0, and in my firewall rules, I allow ssh traffic but not telnet on this interface. Is there anyway I can test this without having a real client machine (I don't want a virtual machine either) that can generate ssh and telnet traffic and exercise the firewall rules?

I'm imagining having a virtual network interface that can forward network traffic to eth0 and back. How can I set it up? Thanks.

KL
