Subject: PPP routing failure

Hi everyone -
I'm experiencing some funky routing failures when I dialup netscape
via user-level PPP:
I can negotiate IPCP fine; get a point-to-point link via tun0:
myaddr:; hisaddr:
When the default route is setup to, all of my packets
blackholed after the first router hop. I am not using NAT.
The PPP link works perfectly fine in windows dialup networking. So I
what is wrong. When I look at the routing table in windows, it seems

default		0		myaddr		ppp
hisaddr		0xffffffff	myaddr		ppp
localhost	0xff000000	localhost	localhost
myaddr		0xffffffff	localhost	localhost
myaddr.255.255*	0xffffffff	myaddr		ppp
multicast	multicast	myaddr		ppp

*this is the first 2 dotted quads of myaddr appended with 255.255

If I try to manually set these routes in 5.3-R, I still can't get
out :(
Setting ADD DEFAULT MYADDR doesn't work, because ppp will still
think MYADDR
is Either I need sleep or something is funky here...
