[pptp-server] PPTP and RedHat 7.2

[Richard Nairn]

Hi,

I have a few machines with RH 7.2 installed on them. Whenever I try and
connect to them with pptp, I get a Gre: protocol not available error. 

Feb 14 10:12:20 gateway pptpd[3806]: CTRL: Starting call (launching pppd,
opening GRE)
Feb 14 10:12:20 gateway pppd[3807]: pppd 2.4.1 started by root, uid 0
Feb 14 10:12:20 gateway pppd[3807]: Using interface ppp0
Feb 14 10:12:20 gateway pppd[3807]: Connect: ppp0 <--> /dev/pts/1
Feb 14 10:12:20 gateway pptpd[3806]: GRE:
read(fd=5,buffer=bfffd6f0,len=8260) from network failed: status = -1 error
= Protocol not available
Feb 14 10:12:20 gateway pptpd[3806]: CTRL: GRE read or PTY write failed
(gre,pty)=(5,4)
Feb 14 10:12:20 gateway pptpd[3806]: CTRL: Client 209.91.117.27 control
connection finished
Feb 14 10:12:20 gateway pppd[3807]: Modem hangup
Feb 14 10:12:20 gateway pppd[3807]: Connection terminated.
Feb 14 10:12:20 gateway pppd[3807]: Exit.


The machine is the firewall, and is not blocking any of the ports or
protocols. I am running kernel-2.4.9-13mppe, and ppp-2.4.1-2mppe.  Any help
would be appreciated, as this is getting urgent.
