I use a similar setup here except I use static IPs for both the ADSL modem
(in bridge mode) and the FreeBSD box connecting to it. The FreeBSD box
then runs a DHCP server (dns/dnsmasq in ports) for any other machines
on my LAN to talk to.

Nothing really stands out glancing at your configs. I'd be looking for
clues in /var/log/ppp.log.

tun0 should have been reassigned a public address here by the remote
PPP host (your ISP). Also the MTU is still stuck at 1500 despite you
correctly configuring 1492 in ppp.conf. So I think the PPP negotiation
is failing. ppp.log may explain why.

Mine looks like this:

tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1492
        options=80000<LINKSTATE>
        inet 58.6.247.132 --> 203.215.15.252 netmask 0xffffffff
        Opened by PID 45904


Below is my (edited) rc.conf & ppp.conf. I simply start & stop the PPP
session with "service ppp start" & "service ppp stop" as root.
