PPPoE Web Gui setup

After some testing of lo:1 loopback settings on my gateway, I was able to determine that the /30 IP does respond to remote pings. However, it did not forward any other connections to my mail server. So instead I removed the lo:1 and added another ethernet card on the gateway, assigning the first /30 IP to it as well as putting it in the red zone. Upon reboot I lost the default route on pppoe. So I added it manually. Then it all worked. I then assigned the next /30 IP to the mail server eth0 port and put it in the red zone.

Is there anyway in the WEBGUI to force pppoe to provide the default route? I think the problem might be that there are two red zone interfaces in two different subnets. I checked the ipcfg-ppp0 file and found a line that reads:

DEFROUTE='no'

Am I correct in assuming that indicates that ppp0 is not set as the default route on coming up?

Current network settings for gateway are:
