MPD PPTP seting 0 on net.inet.ip.forwarding

[Raimundo Santos]

Hello!

I was experimenting with

set ipcp ranges 0.0.0.0 172.16.1.20

to see if I well understood concepts on MPD5.7 docs, but when I try to
connect to PPTP server with 0.0.0.0 as local address,
net.inet.ip.forwarding gets to 0, and the PPP does not connect.

But changing it to

set ipcp ranges 172.16.1.19 172.16.1.20

the same strange net.inet.ip.forwarding going to 0, but it connects the PPP
link.

And by using the mpd.conf.sample ippool example, just changing the IPs to
correspond to my network, the same strange thing.

What a strange behaving. Using MPD 5.7 and FreeBSD 9.2-RELEASE.

What could be wrong?

Here is my mpd.conf:

startup:
        # configure mpd users
        set user foo bar admin
        set user foo1 bar1
        # configure the console
        set console self 127.0.0.1 5005
        set console open
        # configure the web server
        set web self 0.0.0.0 5006
        set web open

default:
    load pptp_server

pptp_server:

        set ippool add pool1 172.16.1.20 172.16.1.100

        create bundle template B
        set iface enable proxy-arp
        set iface idle 1800
        set iface enable tcpmssfix
        set ipcp yes vjcomp
        set ipcp ranges 172.16.1.19/32 ippool pool1
        #set ipcp dns 192.168.1.3
        #set ipcp nbns 192.168.1.4
        set bundle enable compression
        set ccp yes mppc
        set mppc yes e40
        set mppc yes e128
        set mppc yes stateless

        create link template L pptp
        set link action bundle B
        set link enable multilink
        set link yes acfcomp protocomp
        set link no pap chap eap
        set link enable chap
        set link keep-alive 10 60
        set link mtu 1460
        set pptp self 192.168.0.2
        set link enable incoming
    log +all

And here is my rc.conf:

hostname="rtcprime"
ifconfig_alc0=" inet 192.168.0.2 netmask 255.255.255.0"
defaultrouter="192.168.0.1"
sshd_enable="YES"
ntpd_enable="YES"
powerd_enable="YES"
dumpdev="AUTO"

zfs_enable="YES"
noip_enable="YES"
samba_enable="YES"
mpd_enable="YES"

As you can see, there is no gateway_enable="YES", but there is
net.inet.ip.forwarding=1 in /etc/sysctl.conf

Thank you for your attention.
