Please direct me to the right list if I am off topic. I use a UK ISP called freeserve. I have set up a dial-on-demand PPP connection with IP masquerading so that my laptop can act as a router for our small intranet. Everything works fine normally with the ISDN terminal adaptor hooking up when necessary and dropping the line when it is idle for 30 seconds. However, sometimes tasks using the connection seem to lose their way and sit waiting for responses. The command "tail -f /var/log/messages" shows that the local IP address has been changed, presumably in response to some control message from freeserve. My question is, is there any way to lock down a dynamically assigned IP adress once it has been assigned so that is is constant for the duration of the connection? Maybe I can extend the IP masquerading in some way so that the external dynamic IP is directed to a constant local spoof address? I am running mandrake 6.1 TIA Ges Cook
