Two more points here: If you are using a local subnet, is your PPP machine
configured as a gateway (in /etc/sysconfig)? And, if this is the case, how
many IP addresses has your ISP assigned to you?
My subnet works properly because I have a block of 32 nodes assigned to me,
and my ISP is configured to recognize all of them. However, if your ISP is
allocating you only one IP address, and especially if this allocation is
dynamic via ARP or RARP or some such, your ISP is probably disallowing any
packet not coming directly from the assigned machine.
