PPPoE over VPN

Thu Dec 14, 2006 11:31 am

Hi all,

I have a current setup like below: -

Laptop (road warrior) <-- PPTP_VPN --> PPTP_VPN_SERVER <--> MikroTik (with PPPoE server config) <--> INTERNET

I cannot connect to MikroTik's PPPoE server with the above setup. Why?

Regards,
rootlinux

PPTP will not transport PPPoE.
PPPoE works over Ethernet, Laptop and MikroTik PPPoE server should be connected to the same Ethernet network (broadcast domain).
If '<-- PPTP_VPN -->' device is MikroTik router, you can create EoIP+PPTP tunnels, than PPPoE will be transported over EoIP.
I suspect there will be a lot of overhead on this configuration, as PPPoE provides encryption too.
Let us consider most recommended configuration scenario,
1) EoIP, PPPoE. EoIP between <-- PPTP_VPN --> and MikroTik Router, PPPoE is configured on MikroTik router.
2) PPPoE server is configured on <-- PPTP_VPN --> device, then laptop is connected directly to PPPoE server.
