Are you sure the userspace ppp implimentation can do that?
I use NAT over my DSL, and only one of the boxes inside my net can ping
out at the same time. It's not a ppp issue, and I'd be surprised if using
a different ppp made it work. :-)
The problem is that NAT doesn't support it.
Hmmm.... I just tried it, and now it works! I thought it didn't used to.
Either I misremembered, or it's been fixed.
All my machines are running 1.5.
If it really works with userland ppp (which I thought was a downgrade from
1.5's ppp) but not kernel ppp, then there's a ppp bug.
