Hello!

Situation:

I've LAN connected to internet via dialup using ppp (tun0 device) in
autodial mode. My end of PPP link have address x.x.x.x, but ethernet card on
router under FreeBSD 2.1.5 have address y.y.y.y. All connections from router
itself are works fine, but when I try to connect from other LAN's to some 
host in the Internet my router sends any packet in many-many copies. 
I've found workaround for it: tcpdump -i ep0 > /dev/null. If tcpdump is
running than all works fine.

Dmitry.

PS. Sorry for bad english.
