dB of sound pressure level (dB SPL) is defined as: 20 log10 p1/p0 where p1 is actually measured sound pressure level of a given sound, and p0 is a reference value of 20Î¼Pa, which corresponds to the lowest hearing threshold of the young, healthy ear.
The outside refers to the external-facing network interface, the one that receives ingress traffic. In the real world, it is not the case that NAT is simply using a single outside IP; translating traffic into internal IPs and ports. That's what your Linksys router does.
