I've got a box running Redhat 6.1 working as a gateway for our home network.
It's connected to a cable modem, and we've only got one IP address, so it's
doing IP forwarding and masquerading for us.
Now, consider this situation: I've got a * running on one of my windows
boxes, whose IP address is 192.168.0.1 (for instance). The * is on port
8888, and I've got the linux box set up to forward this port along from
port, say, 9999, using a line much like
ipmasqadm portfw -a -P tcp -L xxx.xxx.xxx.xxx 9999 -R 192.168.0.1 8888
in my rc.local.
This works very well for people connecting in from outside - they'd use a
but if I try and use that URL from inside the local network, it doesn't
connect, I'd have to use:
which is rather annoying as it makes it difficult to test things (I have to
VNC out to work and boot up a browser there)
I'm fairly sure the problem isn't with the * software - I've had the
same problem when trying to connected to an apache server inside the network
