You should have add 0 255.255.255.0 HISADDR And in your destination address you must have something, ie you could have: set ifaddr 0 196.123.5.5/24 or whatever, with only the first 24 bits significant. You can only have ifaddr 0 0 for manual dial. In order to dial on demand there has to be some kind of destination address in order to specify a route to the ppp interface. It's quite logical, really. The ppp program only will dial out if packets get to it and they won't get to it if there is no route. I don't know about the inner workings of iijppp, but I know that by specifying that only the first 24 bits of the destination address are significant it is a sort of compromise, but it works. What you say to it is: the destination address can be from 196.123.5.1 thru to 196.123.5.255 This is good enough for setting up the route and when iijppp actually connects it slots the actual address in there and off you go. How to find out what the first xxx.xxx.xxx should be of the IP address should be? Invoke ppp manually with a ifaddr 0 0, ands then type: show ipcp which will show you your IP address and the destination IP address, then use these addresses in your auto dial configuration with a /24 on the end. This means that so long as you are always on the same subnet you will be OK. Soneone else: Has anyone ever tried a /16 in the ifaddr line? Maybe some else can explain this better, and perhaps more technically? > 2. ppp.linkup > > 0: > 0 255.255.255.255 HISADDR Here I have: MYADDR: delete all add 0 255.255.255.0 But I do not think it is necessary for -ddial, as the line in ppp.conf add 0 255.255.255.0 HISADDR Has already set up a default address. > But I start the ppp -auto uunet, I got the following message > > User Process PPP.

It should at least dial out first > and before it finds out that it is reachable or unreachable. See above. Sorry this was so long and rambling but I am writing as I think which is fast but sometime confusing.
