My first post here and I am fairly new to Linux. I am running a network and using ipcop to dial up a 56k line and also a 64k isdn line, as there are two channels on isdn and my isp does not support 128k, I would like to use another ipcop machine to dial the second isdn channel. I don't wish to move to another isp as I am very happy with the current, in addition, I can also create another cache with the new ipcop machine. My question is how can I force the two ipcop machines to only use their dedicated isdn channel, is there a fix I can install? Has anyone else tried this or know how to do it? Thanks in advance.
