I have looked for the answer to this question to no avail, apologies if I missed it.
I would like to know how effective iptables
would be against MitM attacks - in the following setup:
ALLOW INPUT {only one IP address}
DROP All Else Anywhere
I guess what I am asking is, would it still be possible for someone to masquerade as the one allowed IP to connect and prepare mitm attack on any incoming connections?
Also, what if the connecting device had the same iptables
configuration, allowing only the first device's IP...
You'd think that would be a fairly secure setup - but I want to be sure...
