Packet Editor
 

i have a question about packet editing. i'm trying to break firewall rules by changing the data associated with a packet, so that the packet is recognized and allowed, but the data within is malicious. is there a tool to do that, or am i making an unreasonable request.

If the packet is malformed in any way most firewalls will drop it.

we're hoping that's what happens, but we just want to make sure.

Monitor both ends of the firewall and you should determine if packets are allowed or not. "Edit a packet"
What do you have in mind?

haha, i guess we're not quite sure what we want to do with it either. i'm kind of new to this, but the idea sounded good in my head. if i get some more, or more specific, information, i'll post and let you know. thanks anywise.

So, basically you're admitting you're wasting the time of people trying to help you?..

I don't know if that's a valid analysis. I think he's just admitting to a nebulous idea that he wants to define a little more clearly.

anyhow, darthczyz you can do what you want, but it'll involve hacking your tcp/ip stack.

there are network testing tools out there... one company of note is midnight networks. a friend of mine used to own the company but was bought out a few years ago. as far as I'm aware, they still make test suites, and you can probably get demos that'll do what you want.
