[TriLUG] ATT gigabit internet quick review

[Rogers, Matthew via TriLUG]

So in DMZ mode the DMZ device shows the external IP which it pulls via DHCP.  The ATT device just forwards all traffic to that particular port unless it has something in its state table since the ATT router is still running.  I turned off the wireless on the ATT device.  It’s important to note that the ATT device uses a particular subnet 192.168.1.0 or whatever, but prior to the DMZ mode being used – the new router will pull an internal IP prior to configuration of DMZ plus mode.  If you duplicate that subnet you’ll cause a problem during that configuration change.

You can set a device in dmz plus mode which is basically a bridge mode.  I do this and run my own router and domain controller with dhcp/DNS etc.

Do you end up with double-NAT using DMZ mode, Matthew, or does your router get the external IP address?
