Most firewalls won't let you connect to the external address assigned to the firewall from inside. The solution to that for most is to add a line to /etc/hosts that short cuts the lookup to po... [by TrevorH]

On a LAN each computer is assigned a different IP address each morning. When I installed Kubuntu 12.10 the IP address assigned to the machine was '10.0.0.2', but today it is '10.0.0.1'. When I try to connect to 'http://127.0.0.1' in a web browser I see in the status bar 'Connecting to 10.0.0.2'.
I'm trying to convert an old Pentium III I had lying around into a firewall and decided to use Devil Linux. I have a dual port adapter I'm using to connect to my router and my desktop on eth0 and eth1, respectively.
I'm on a corporate computer that is behind a very restrictive firewall, and trying to connect to my home computer.
I configured my router to forward port 80 to 3389 (RDP port). My idea was to try to connect with port 80 since the regular RDP port might be blocked.
However I found out that it's not working.
Now I dont often have to mess with my local network but I have an application which needs to use dns lookup to find another PC on my local lan (it assumes anything in its config to be a name and not an IP address!)) so what I thought I could do was to add the relevant name and IP address to my /etc/hosts file and after a restart any request for the defined host name would be returned the IP addres
Is it possible to add scripts (like curl) to /etc/hosts? I am trying to set up a subdomain over ddns, and it's really hard to update my /etc//hosts file on the fly when my IP address updates without my knowledge. Thanks in advance.
I have just setup an F17 box as a firewall. Everything is working fine, except for one minor catch: In short, the firewall box itself cannot access any services (eg, dns, ntp) unless I explicitly open up ports for them on the wan interface.
