From personal experiance and help from many people on the NetBSD lists.
The first time I ran up against this problem was with a
Mac IIci running 1.3 then when I installed 1.3.2 on a i386 box
I encountered the same problem.
Yes the kernel-sources need to be patched.
The file /sys/netinet/ip_nat.c needs patching.
Third where and how:
The patch for 1.3.2
ftp -a -p
patch -p1 -E <diff-ipnat
now you need to remove all the old files from ( build directories)
in each directory you find there.
( replace <XXX> with your hardware name. eg. <alpha>)
Now you should be set to build a fresh kernel.

Static-meaning the IP number on each end of the ppp link is always the
Heresay only. I have not attempted demand dial.
pppd - Point to Point Protocol daemon
demand Initiate the link only on demand, i.e. when data
traffic is present. With this option, the remote
IP address must be specified by the user on the
command line or in an options file. Pppd will ini-
tially configure the interface and enable it for IP
traffic without connecting to the peer. When traf-
fic is available, pppd will connect to the peer and
perform negotiation, authentication, etc. When
this is completed, pppd will commence passing data
packets (i.e., IP packets) across the link.
When the demand option is used, the interface IP addresses
have already been set at the point when IPCP comes up. If
pppd has not been able to negotiate the same addresses
that it used to configure the interface (for example when
the peer is an ISP that uses dynamic IP address assign-
ment), pppd has to change the interface IP addresses to
the negotiated addresses. This may disrupt existing con-
nections, and the use of demand dialling with peers that
do dynamic IP address assignment is not recommended.
