So I beleive we should assign a private address (RFC1579) > avoiding confliction in world. 0.0.0.0 is an invalid address (unlike the RFC1579 addresses). So if some peer is suggesting it, the actualy address *must* be negotiated by the IPCP peers. The RFC1579 addresses are valid, but should not be routed. Anyway, it would still make sense to use them for private PPP links. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
