said by OldCableGuy :So what happens when you're traveling and don't have access to your static IP?
Your lack of planning tells me you have not thought this through much at all if at all, period.
Also you clearly have never heard of IP spoofing, I could send packets to your device forged as any IP on the net if I wanted to.
What you're suggesting is the same as turning off all encryption on your wifi and doing MAC filtering, laughable security at best.
I'm not sure if you're read the thread...but I'm not looking to replace my already existing VPNs and VLANs to simple iptables IP blocking.
Also, I'm not entirely sure where your attitude comes from.
My simple question was if Mediacom could provide me a static IP. Can source IPs be spoofed..yes, does that mean nobody should use them as a security layer even if it adds very little benefit? No.
