Hi All, I've read and scanned everything I can think of but I can't find any information regarding on-demand dialing to an ISP when the gateway IP is dynamically assigned. I do have ppp running just great, definining all the proper routes (including the default) and (a major accomplishment for me :-) setting the correct netmask (didn't realize it was a param on the set command). In any case, I have a new ISP that has assigned me a static IP address. However, the gateway IP is dynamic (depends upon the portmaster I get). Given that, I can't figure out how to setup the tun0 device with the proper default route such that ppp -auto will work correctly and reliably time after time. Basically I can usually get it to work for the very first time... but when the connection drops it deletes all of the routes. So far I: 1) ifconfig tun0 up 146.x.x.x 199.y.y.y netmask 0xffffff00 2) route add default 199.y.y.y 3) ppp -auto ultranet When a connection is made, ijppp does: ppp.conf: set ifaddr 146.x.x.x 0 255.255.255.0 ppp.linkup: delete ALL add 0 0 HISADDR Please note that the 199.y.y.y address listed above is sort of a fudged number. I really don't know what address I'll get, so I just use the address of one that I know. I assume the system will delete the address once the connection is made. Does someone have a list of available commands used in ppp.conf and ppp.linkup that might help me out? Thanks for any help! - Jeff
