My ISP recently assigned me a routed subnet - let's call it 206.x.x.104/29 (255.255.255.248). They said that this routed subnet is "behind" the IP that is assigned to me automatically via PPPOE.
When I take one of those usable IPs (like 206.x.x.105), assign it to a VLAN called "206" on the router, and then get my laptop on that VLAN, I can see the router. The router can see me. The router can see the internet. The laptop cannot reach the internet.
I've turned on ip route. I've set the default gateway to use the Dialer1 interface. The PPPoE connects fine, I just can't get the VLAN 206 to see the internet.
Of course, when I enable NAT for the VLAN 206 (set VLAN 206 up for "ip nat inside", and set Dialer1 as "ip nat outside"), the VLAN 206 can see the internet, but nothing on the internet can see VLAN 206 since it's NATed.
Also worth noting: a traceroute from another place on the internet to an IP address in my routed subnet 206.x.x.104/29 never seems to reach my automatically assigned PPPOE IP. Any good advice out there?1811WorkInProgress.txt
