I've got a new Edgerouter Lite to take care of handling a PPPOE connection from an ISP and serve as the gateway for a few firewalls that will be hanging off a switch on another interface. The proposed setup is in the diagram below.
Interface pppoe0 on edgerouter gets an IP address when it connects (1.2.3.4/32)
I added an address to edgerouter eth1 (1.2.3.5/29)
I assigned an address to a WAN interface on one of the firewalls
The firewall can ping the addres on eth1, but cannot ping the address on pppoe0. I can however ping the address on eth1 from another host on the internet.
Other than upgrading firmware, setting up new admin user, and disabling ssh/web management on the WAN interface, the configuration is stock.
Let me know if you can tell what I am missing to get the Edgerouter to route traffic for hosts attached to the switch on eth1.
