LAN/WAN IP address and http to virtual server behind DSL modem
I've set up a virtual host on my linux redhat 8 OS. It uses DNS, and that works fine. I can dig it, ping it, telnet it, ftp it, and http it. But this only works when I'm doing it on y Linux OS. This computer is part of a network behind a DSL modem, and the other computers in my network cannot ftp/telnet/http it, even if I use the LAN IP address, it doesn't work.
Furthermore, I cannot http to it over the internet, using my WAN IP address, even not on my Linux machine. It only works with my Lan IP address.
Can anybody help me configure the network so I can http it from outside my network (or even on my other computers within my network)? I don't have a static IP address, but I take note of it and use it before it changes.
