Re: PPP over Ethernet?

Nah, They never heard of virtual circuits.

Seriously, PPP over IP is a way of building a cheap VPN. The thing is that SSH already does that job much better.

The SSH FAQ or docs or whatever mentions that there is a big problem with this type of tunelling: If TCP traffic goes through the tunnel and congestion is encountered, both the TCP traffic being tunelled and the tunnel itself (which is a TCP connection) will retransmit, causing, at the very least, a waste of bandwidth. Maybe other kinds of havoc could result from this? That is why I thought protocols like GRE which encapsulate one packet in one packet were much better. -Phil
