Are there any guides or howto’s on how to best setup a server that’s going to sit inside an internal network, behind a firewall (NS or otherwise), as when I very briefly looked at this, there were a number of hurdles I hit. I didn’t go any deeper, as a single NS instance does what I need. (At least today).
Things like the network, as there will probably only be a single NIC, and NS appears to be more geared to multiple NICs. Also, firewalls, as even if you don’t select any of the firewall options from the Software Center, Shorewall is still installed and configured, so you have a firewall blocking access to the server and no way to control it.
I’m sure there’s a bunch of other gottcha’s that would be useful to know about when setting up a multi-NS environment.
