Proxy / reply translation

[Richard J Palmer]

HI

This is where my skills are not great (regex) most other areas I can 
work with. Ultimately I am happy to pay someone to help write the 
little bit of code that does this. I do need to cope with Netmasks 
from  /32 to /24 so a few switch cases.

Alternatively if someone can provide a few pointers on that bit I can 
probably build from there.

Again I am not expecting something for nothing - so if it needs an 
hour or so's work I am happy to reward for that
