There is no need to use ifconfig for tun0. iijppp does everything by itself. > Secondly I was going to say that it sounded like a good idea > to alias lo0 with your hostname but I tried it and it did*not* work with ppp. What does lo0 have to do with ppp? I think they even do not know about each other. How exactly did it not work with ppp? I think it would be a good idea though to take different addresses for lo0 alias and for /etc/ppp/ppp.conf to avoid confusion. Say, 192.168.1.1 and 192.168.2.1 Please IP experts correct me here. > As I said before, I ended up with a 'my addr' of 192.168.0.1 and of course the > ppp session failed. If you mean the "ifaddr" statement in your /etc/ppp.conf file, try set ifaddr 192.168.0.1/0 thus allowing iijppp to assign ANY address received from the ISP to your tun0 interface. > > > > > I have dynamic assigned address.
