I am setting up 3 sites to be "reverse proxied". Everything within
NWAdmin seems to be ok and the Proxy screen on the server shows them
loaded also; however the sites will not responding.

Which IP exceptions do I need to let requests in and info out?

In (for each site)
NICs: All - Pub protocol: http Destination: <secondary IP address>

Out (for all)
Pub - All dyn/tcp All

Does that look right?
