I had an additional address created before installing 7.080, which was used to access my DSL modem. It never went to status UP.
After a reboot, it was status UP, but it was created as a subinterface off ppp0, so it shows as ppp0:yfkKGW.
ppp0:yfkK Link encap[:P]oint-to-Point Protocol
inet addr:192.168.99.4 P-t-P:192.168.99.4 Mask:255.255.255.0
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1452 Metric:1
I have deleted the entry in WebAdmin, however it is not removing the ppp0 subinterface.
