Web server behind a firewall

Is it possible to have a webserver behind a
masquerading routing machine? Would the concept
be mapping connections to a port in the router to
ports of the (inside) server? Something different
I am not aware of?

TIA

I assume by router you meant firewall? But essentially yes. You "map" a
port on the external interface to forward to an ip_address/port on an
internal system running the web server. There are numerous howto's to
accomplish this. Personally I use fwbuilder to manage my firewall
rulesets.

Really depends on what firewall/router you are talking about, some
don't even handle port forwarding.

you can even run the server on a def port and fwd the port form the
smooth wall to the server
