pptpd problem

[Sergey Smirnov]

Hello,

I'm trying to set up VPN server on FC5..
Using software:
kernel-smp-2.6.17-1.2174_FC5
ppp-2.4.3-6.2.1
pptpd-1.3.3-1.fc5

config files:
__
/etc/pptpd.conf

option /etc/ppp/options.pptpd
debug
localip 10.25.100.10
remoteip 172.16.10.1-100
__
/etc/ppp/options.pptpd

name pptpd
lock
auth
require-chap
nodefaultroute
nodeflate
nobsdcomp
nomppe
__
/etc/ppp/chap-secrets
test    *       test    *
---
Loaded modules:
...
ip_gre
ip_conntrack_pptp
ppp_async
ppp_generic
...

On other FC box, I'm trying to up vpn link (only testing):
#pptp 10.25.100.10 name test

In /var/log/message on VPN server:
...
pptpd[4405]: CTRL: Client 10.25.100.100 control connection started
pptpd[4405]: CTRL: Starting call (launching pppd, opening GRE)
pptpd[4405]: GRE: Bad checksum from pppd.
pptpd[4405]: GRE: read(fd=9,buffer=8059660,len=8196) from PTY failed: status 
= -1 error = Input/output error, usually caused by unexpected termination of 
pppd, check option syntax and pppd logs
pptpd[4405]: CTRL: PTY read or GRE write failed (pty,gre)=(9,10)
pptpd[4405]: CTRL: Client 10.25.100.100 control connection finished
...

Any ideas?
