[pptp-server] New on setting up pptp,help!

[Zhu Xiaofeng]

Hi everyone:
 When I install pptp on my FreeBSD 4.0-release and start pptpd,a message is
added into syslog as following:

    Nov 25 20:09:40 freebsd pptpd[19435]: MGR: Max connections reached,
extra IP add
    resses ignored
Then when system already has a user connected , second user can't dial.Log
messages follows:
    Nov 25 20:03:50 freebsd pppd[19409]: pppd 2.3.10 started by xfzhu, uid 0
    Nov 25 20:03:50 freebsd pppd[19409]: ioctl(TIOCSETD): Device not
configured
    Nov 25 20:03:50 freebsd pptpd[19408]: GRE:
read(fd=4,buffer=804da80,len=8196) from PTY failed: status = 0 error = No
error
    Nov 25 20:03:50 freebsd pptpd[19408]: CTRL: PTY read or GRE write failed
(pty,gre)=(4,5)

    Can somebody tell me why to correct it to let more user dial onto system
vi pptp?
