I followed the tutorial on the main site here to get PPTP VPN setup. I was doing this on an extra RT-N16 router. I tested the VPN connection by setting putting the WAN port of the VPN router on a LAN port of my main router. While connected to the main router I was able to VPN into the VPN router just fine. I then removed the main router and put the VPN router "in service" and now I cannot get VPN connections to work again. I use PPPoE connections for my WAN which appears to share some similar components as the PPTP since my chap-secrets were destroyed. I re-added my users/pwds but I am getting the below GRE error. I did validate options syntax but cannot find pppd logs. Any help is appreciated.
