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,
I've fixed these two issues with ppp(8), please check the PRs: bin/130159
and bin/131250.
If it works for you please let a note and maybe someone commit this.
Best regards,
Luiz
