I want to be able to redirect outgoing http requests from the box back to local addresses on the box... In reading up, it appears that the redirect config line should do that, and in testing, I have a simple line like this in the pf.conf rdr pass inet proto tcp from any to 209.131.36.158 port 80 -> [internal address here] port 80 now, I haven't made that internal address be an address on the local box yet, cause I'm testing to see how this works... I can manually telnet to [internal address here] port 80 with no problems and get the apache greeting. Once I turn on and load the pf.conf file (with pfctl -F all -f /etc/pf.conf), and I try to telnet to 209.131.36.158 port 80 (generic www.yahoo.com), I don't get redirected to the internal address port 80 and get the apache greeting that is expected... I did turn on port forwarding as per the instructions for NAT, although it didn't say if it was needed for rdr. net.inet.ip.forwarding=1 in netstat, I see it trying to actually reach the ouside IP, which it cant, so the translation didn't appear to take affect... am I missing something ? Thanks, Tim.
