by i am running seawolf redhat 7.1, php 4.1.2, apache 1.3, and using iptables.
"Gate" is my gateway with an external eth, and an internal eth. "Mac" is in
my lan. i have an application that runs Mac, listening on port 23000. Gate
runs php and apache and the firewall. Gate forwards packets on 23000 to Mac.
i asked a friend to telnet in to my external ip on port 23000, and Mac
receives all the forwarded data. when i try to telnet to Gate's external ip
from within my net (ie., not from Gate, but from Mac) the packets get to
Mac. but when i try to telnet from Gate, i get "host destination
unreachable" on that port.
a php page (on Gate) that open a sockets to send packets to Gate's external
ip, which should then be forwarded to Mac, gets "error: 111: connection
refused". if i change the ip in the php script to Gates' internal ip
(192.168.0.1), the packets get forwarded.
does this sound like something obvious that i overlooked? can php connect to
the external ip of the machine it is running on? i would think it can.
any suggestions are appreciated.
