2021-03-01nat: pick outside addr based on local addrKlement Sekera6-107/+215
Use outside addresses more evenly by using local address to pick from pool of addresses. This ensures stability from POV of remote host - an internal host always gets translated using the same outside address, so it doesn't appear to be "hopping". Also, this avoids all hosts being translated using the first address, which helps avoid needless recaptchas and the like. Exact assignment depends on internal ordering of addresses - local address is used to pick an offset into internal vector. If that address cannot be used, a linear search is performed as a fallback mechanism to find a possible translation.
