Couldn't you use the "LOCAL IP:REMOTE IP" function in your options file:
192.168.1.1:192.168.1.100
Your machine's local IP:The Ip you want to give the caller
If you put this option into a file specific to your dial in device, then whenever
somebody calls the phone line on that device the options file will allocate the
appropriate IP address for that device. This happens regardless of what interface
(ppp0, ppp1 or whatever) is allocated.
The device specific file should follow this naming convention:
/etc/ppp/options.ttyS0
/etc/ppp/options.ttyS1
/etc/ppp/options.ttyS2
.....
If you read the ppp man page you will find, that ppp when activated (for example by
mgetty or manually) will first read the command line options, then the general options
file (/etc/ppp/options), then the device specific options file
(/etc/ppp/options.ttyS0).
Somewhere in there are also user specific options. I have never used that so, if you
need to, look it up.
I hope this is what you meant.
