>Description:
      in freebsd-4.11 i used to use pppd in on-demand mode, with active-filter containing 'outbound' keyword, so that connection could be held up only by packets sent from my host, not from the outside.  that's to prevent some malicious attempts to held it up.  after migration to freebsd-5.4, the 'outbound' keyword is no longer accepted by pppd(8), nor tcpdump(8) - it fails with 'inbound/outbound not supported on linktype 9'.

>How-To-Repeat:
      tcpdump -i ppp0 outbound
