Just a quick followup: I've finally figured out a workaround. A hack, to be sure, but a workaround nonetheless. I've created a shell script called /etc/ppp/pppfix, which looks like this: #!/bin/sh # Fix up PPP routes sleep 1; logger -i -t ppp Fixing route: route change -host $1 $2 -ifp $3 route change -host $1 $2 -ifp $3 I invoke this from the relevant section of /etc/ppp.linkup with the line !bg /etc/ppp/pppfix HISADDR MYADDR INTERFACE Note that the "sleep" may not be absolutely necessary, but it seems like a good idea just in case there's a race condition. I also added the following lines in the relevant section of ppp.linkdown: iface clear delete! HISADDR delete! ALL shell arp -d HISADDR quit all I found that if I did not do this, the modified route persisted after the connection terminated. The "arp -d HISADDR" should only be used if proxy arp is being done, and may not be strictly necessary; I wanted to make sure I tore down any residual proxy arp entry. Of course, all of this is an awful hack and the relevant code in userland PPP still needs to be looked at. --Brett Glass
