[44net] Help with first time setup on a edgerouter

HI After receiving my ip address assignment i am trying to set  44net up on my edgerouter 8. Following the instructions for the edgerouter on the wiki, and changing the port from eth2 to eth7 i as unable to ping thru to the internet as described in the instructions. An edge router 4 was also set up using the wiki instructions and the same result of not being able to ping thru to 8.8.8.8 on the edgerouter 4, thus i am continuing with the edgerouter 8 as this would be my final configuration. In order to test my configuration, a edge router 4 was programmed to simulate the UCSD end of the tunnel and a Layer 3 switch was used to simulate the internet connection. The test setup as able to pass the IPIP traffic between the routers as expected, this leads me to believe i may have the setup correct or at least very close. now i am at a loss of how to troubleshoot further. Any advice, tips, troubleshooting methods, or help of any kind is greatly appreciated. Thank you Chris
