I am trying to set up my old FortiGate 100A as a simple router for a small office network. My ISP's incoming PPPoE connection runs on VLAN 100 and I can't seem to get it going on a WAN port of the FortiGate. I have created a VLAN sub-interface under one of the WAN ports and got it authenticating and getting an IP address from the ISP, but I can't seem to get it passing traffic from the internal interfaces through that sub-interface.
I have tried setting a static route, but as i understand it, I shouldn't have to do that, because the gateway is retrieved from the ISP when it connects.
I am pretty new to the whole "real" router scene so I might have missed an obvious step I don't know about.
If you need any more information, let me know.
