[pptp-server] gre protocol not available - help!

[Örjan Johansson]

I just looked through my .config file, and it says CONFIG_NET_IPGRE=y so
the line in modules.conf is as vain as I suspected right? The utterly
confusing thing is that once or twice I've got it working, without doing
anything...... So why is the protocol not available 9 times out of ten?
Any ideas at all?
 
Cheers,
Örjan

	Did you actually compile gre as a module?  You must select it in
your kernel
	configuration.
