There is a LAN of a dozen computers. One of them on port 3000 hangs the web interface of mantis. It is perfectly open at 192.168.31.12
:3000. As a method of Internet access in network is using ADSL modem DLINK with a static IP on which you have configured the forwarding port 3000 on the computer 192.168.31.12 — thus the required service is also available from the Internet at our static IP
But here's the problem: when one user gives another link to the bug tracker — he never knows where the second one this link will open — from local area or from the Internet. As a result, the links constantly have to change the internal IP address to external and Vice versa. The problem is compounded by the fact that the bugtracker sends mails with links to tasks, and these links are, again, working either from local area or from the Internet.
Could we set up something (a forvarding of ports, the routing, the modem, bugtracker) so one link (say, using a global static IP) the web interface was up and running in the local network and from the Internet?
