The following one liner can get the IP address
of your ppp0 interface.
ifconfig -a | gawk \
'/^ppp0 / { getline ; split ( $2, a, ":"); print a[2] }'
But, I see that's not what you're asking for.
I think you could use the /etc/ppp/i-pup script that's
called by pppd whenever it as established a connection.
The local IP address is the fourth command line argument
to that.
There might be a race condition between the route
establishment and the enforcement of these rules.

Why specify any source address here?

Why specify the destination address here.
