Jason:
Your ppp link's ends are on different networks

localip 192.168.0.50-80                 << These need to be
remoteip 192.168.1.50-80             <<  on the same subnet

ie:
localip 192.168.0.50-79
remoteip 192.168.1.80-110

This needs to match you LAN if you want to access machines on the LAN
