>Description:
On an incoming ppp connection, ppp assigns the wrong interface name to an added network route.

This means that the new newtork can not function.

-----8<----- extract from ppp.conf

incoming:
 enable chap
 disable pap
 accept dns
 set ifaddr 10.1.7.1 10.1.7.2 255.255.255.0
 set dns 10.1.0.254
 set nbns 10.1.0.254
 # enable proxyall
 add 10.1.5.0/24 10.1.7.2  <<

The route must be deleted by hand and re-added giving:

10.1.5/24          10.1.7.2           UGSc        0        4     tun0




>How-To-Repeat:

Have one link dialed out using kernel ppp (pppd) and one link dialed in using user ppp.
