OK, lets look deeper.

Do you have a static IP address, or is it allocated each time you connect?
Is the IP address you connect to (i.e. your ISP's router / host) fixed
or variable?

Assuming the answer to the above is both fixed, my setup should get you
started. Note that I have a local ethernet with bogus IP addresses,
which complicates the picture a little. For my FreeBSD machine with the
ppp external connection the setup is as follows; the local ethernet
address for this machine is 10.0.0.2, hostname freebie. Just ignore
all references to that name / address and the 10.0.0.0 network if you
don't have the same situation... (Stuff in square brackets is commentary,
it's not in the files.)
1. /etc/sysconfig:
network_interfaces="ed0 lo0"
ifconfig_lo0="inet localhost"
ifconfig_ed0="inet 10.0.0.2 netmask 0xff000000"
[stuff elided
NOTE - no ref. to 'tun0']
static_routes="loopback freebie multicast"
route_multicast="224.0.0.0 -netmask 0xf0000000 -interface localhost"
route_loopback="${hostname} localhost"
route_freebie="freebie localhost"
[NOTE - no static route to ISP]
# Set to the host you'd like set as your default router, or NO for none.
defaultrouter=NO
2. /etc/ppp/ppp.conf
#
# Default setup. Executed always when PPP is invoked.
#
default:
set device /dev/modem
set speed 115200
set timeout 300
set debug chat
# asyncmap 200a0000
# escape 11,13,ff
# disable lqr
# deny lqr
set dial "ABORT ERROR ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 2 \"\"ATs0=0s11=50B
1E1L2M1N1TQ0V1W0&K3s37=15s95=47M0 OK-AT-OK \\dATDT\\T TIMEOUT 30 CONNECT"
[stuff elided...]
ondemand:
set phone 7414791
set login "TIMEOUT 30 ease?-\\r-ease? PPP ame: xxxxxxxx word: xxxxxxx"
set ifaddr 166.84.193.118 198.7.0.124
add 0 255.255.255.0 198.7.0.124
[NOTE: my dialup IP address = 166.84.193.118, ISP's router = 198.7.0.124,
'add' line sets default route, when connected]

Naah, doesn't sound like it. It's probably something really small, though.
By the way, are you running named?
