[pptp-server] Help ! GRE: Protocol not available

[L.Fernando]

Hello all

I installed PoPToP v.1.1.2 with RedHat 7.2 (kernel 2.4.7-10) and have the
following error in my pptp.log file:

Jan  9 11:27:11 LFS pptpd[13270]: GRE: read error: Protocol not available
(Complete message included below....)

So, could you please help me with that matter ?

Thanks in advance,

Fernando.
