As mentioned above - just use BRIDGE MODE and be done with it.

No, you put the hosts file on WHATEVER box or boxes that you would have put the BIND server on, or put it on the edge firewall and set the internal workstations to use the edge firewall as their DNS source. The trick is to enforce that ALL workstations only use the box(es) that have the host file. T...

However, I'm looking for configuration ideas to use my own bind server to accomplish the filtering. Unless you have a very short whitelist, and plan on banning EVERYTHING else, you can't - it would take more then a full time staff member to keep your filters up to date. If you have a short whitelis...

As long as you have a copy of the old server - pay for results. If the "expert" actually does move everything across and it works per your specifications, then Yipee!, if not, don't pay the guy.

Personally, I would install Windows 7 on the 1st HD and format the 2nd HD as NTFS. Then install the free VirtualBox on Win7 and setup two VM's on the 2nd H...

Why do the uninformed think that hardening a FULL BLOWN distro into something that kindof sortof almost is a firewall is just a few google articles away? Take a quick peek at the source code for a real firewall (like PFSense or IPCop) and then tell us your grand plan for converting a FULL BLOWN Dist...
