Hi,
What about adding
disable iface-alias
iface-alias
Default: Enabled if -nat is specified. This option simply tells
ppp to add new interface addresses to the interface rather than
replacing them. The option can only be enabled if network
address translation is enabled (``nat enable yes'').
With this option enabled, ppp will pass traffic for old interface
addresses through the NAT engine (see libalias(3)), resulting in
the ability (in -auto mode) to properly connect the process that
caused the PPP link to come up in the first place.
Disabling NAT with ``nat enable no'' will also disable
`iface-alias'.
