After reading bits and +pieces of a few random websites (including various ServerFault posts), on an +inkling I added the line `interface = "bge0";` to my `/etc/jail.conf` file and +ran `service jail restart www` (`bge0` is my LAN interface on the host). After +`jexec`ing in, I tried `pkg install nginx` again and it worked like a charm! + +<!--more--> + +I also noticed that when I run `ifconfig` on my host now, both the original +10.0.2.201 and the jail's 10.0.2.202 addresses had been added to the `bge0` +interface. I wondered whether that meant that I could now SSH into the host +using the jail's IP address. So on my laptop, I ran `ssh bb@10.0.2.202` and lo +and behold, it worked. The opposite, however, is _not_ true: loading +http://10.0.2.201 in a web browser does not give me the beautiful "welcome to +nginx" page that http://10.0.2.202 has. + +I'm sure some trickier stuff will arise when dealing with NAT and multiple +interfaces, but for now I'm satisfied that I have a basic understanding of how +to set up a service in a jail and expose it to the network. |
