By default 198.69.104.232 is invalid address wrt netmask 255.255.255.248
because of zero host bits. You have menu of three choices:
1. Remove netmask of pointopoint interface, it is non-sense.
2. Change this address.
3. Make "ip route del broadcast 198.69.104.232 dev ppp0 table local", which
will make it usual unicast address.
Choose one which you like more. I'd prefer the first.
