I don't think this is the right distinction; really, you have a list of
'known' hosts that you don't need to go through the proxy to reach, and
you go through the proxy to reach the 'unknown' hosts. And, in Asterisk
1.6.x, you can already set the outboundproxy setting at the general
level and on a per-peer basis. So, for all your phones/internal
servers/etc., just set them to not use the proxy. In fact, this is even
better when one of your 'internal' phones happens to be registered from
a non-'localnet' IP address.
