If you put a hard-coded ``add'' line (ie, one without HISADDR in it), ppp simply runs it. You can probably get away with changing your add line to add 10.1.5.0/24 HISADDR so that ppp re-adjusts the route when the interface address changes, or alternatively (and more correctly), put the above line (with HISADDR) in ppp.linkup so that it's added *after* the interface has been negotiated and set up. -- Brian <brian@Awfulhak.org> <brian@[uk.]FreeBSD.org> <http://www.Awfulhak.org> <brian@[uk.]OpenBSD.org> Don't _EVER_ lose your sense of humour ! Responsible Changed From-To: freebsd-bugs->brian ppp's mine. A followup is on it's way State Changed From-To: open->closed This is a configuration error Thanks Brian! :)) Maybe someone should change the 'man' page for ppp. I had a problem with the man page! It said :- it is possible to use HISADDR, MYADDR .... It does not say that the link will be given a random interface name if you DO NOT use HISADDR. Or say it is important that you use HISADDR for new incoming IP addresses............just traps for newbies I suppose :) It also does not help when you read the 'man' examples of 'add' like this.... ------- start ppp man entract > >The entry in /etc/ppp/ppp.conf on awfulhak (the initiator) >should contain the following: > > ui-gate: > set escape 0xff > set device ui-gate:ppp-in/tcp > set dial > set timeout 30 > set log Phase Chat Connect hdlc LCP IPCP CCP tun > set ifaddr 10.0.4.2 10.0.4.1 > add 10.0.2.0/24 10.0.4.1 << ---- END ppp man extract Maybe this should read "add 10.0.2.0/24 HISADDR" instead.

Ah, yes, this stuff is a bit wrong :-I I've made some modifications. Please let me know if they don't make sense.
