Whoa! doesn't DNS have to look outside to resolve names? If you send a packet
destined for the outside wouldn't PPP attempt to remake the connection?
Of course leave the things that you want in to start the connection. I filter
everyting and leave only ping, so to start my connection I ping my ISP.
I assume that it's ijppp you are
running if so you don't need to rebuild the kernel to fix the problem, it's
just a configuration issue.  If it is kernel PPP then I don't know what is
the problem but I suspect it's the same configuration issue.
