I have stared at this, and looked at the sample a kazillion times, and
I just tain't seeing it.
A 4.2-RELEASE box is working fine with a similar config, but
a 4.2-stable box from 1/10/2001 is having trouble.
ed0 is on a private network (192.168.101.2), albeit it has static routes to
a couple other subnets.
So the intention is to just dial in, start ppp, add a default
route, do my thing, disconnect.
If I don't do add default HISADDR's in the config file, then
I can ping the peer IP. I can *never* ping the tun0 IP,
for reasons I don't understand.
I can usually ping the peer, and if I add a default route by
hand, I can usually do some stuff.
I just do 'ppp -nat -foreground papchap'
ifconfig/Routing table with this ppp.conf:

And if I add a route by hand to the default, it works:
xyzzy# route add -net default 63.164.160.71
add net default: gateway 63.164.160.71
xyzzy# ping ns-01

64 bytes from 204.118.244.2: icmp_seq=0 ttl=251 time=218.460 ms
Now, all I do is do the "add default HISADDR" in ppp.conf:
Dial again, and nada.
What's weird is that the NAS box I'm dialling into shows 0 bytes in on
the serial interface when it's frozen. Nothing in ppp.log stands out
it just doesn't work.
The ppp.conf:
