why not just 1
ipfwadm -F -a m -S 10.0.0.0/32 -D 0.0.0.0/0
instead of 1 per IP?
that way all of 10* gets the ip masq forwarding?
(thats what I use)

or... in /etc/init.d/local.ipmasq (I use local. to prevent conflicts)
then it will set it up on reboot every time...
I have found this isn't a problem when the ppp link is downb either.

yup...and if you wanted a class B instead of a class A or C (I use the class A
10.* myself) hmm I can't find the numbers...
could have sworn it was in RFC 791...which references assigned numbers...
rfc790....hmm...I don't have that one...oh well
BTW just as a note...
I noticed that the other end of my PPP link is often 10.* ;)
makes sense tho...afterall...my ISP doesn't really need its ppp servers
to have REAL and acessable IPs ;)
