Yesterday, I used this guide to set up my Ubuntu Server installation as a router with a simple firewall. I was able to access the internet, but after I installed a PXE server along with the router using this guide to network boot Ubuntu Desktop, I couldn't access the internet anymore. (I can still open Webmin and SSH to the server, though). Right now, I have to choices: either boot the local hard drive to access the internet, or boot from the PXE server and have no internet. I want to be able to boot from the PXE server and still have access to the router part. Is this possible?
Note: The NIC card I'm using to network boot is the same one as the LAN side of the router.
