How can I send a 0.0.0.0 local ip address to my isp?
The problem was about an ISP who acks any requested local address except 0.0.0.0.
I've done a bit more work on this, and have a suggestion for a patch to ppp.
The issue only arises in demand mode. If pppd is coming up at the same time as the
link,
an initial local ip address of 0.0.0.0 specied on the command line is ok.
In demand mode, an interface has to be set up with some valid ip address as soon
as pppd starts, long before the link is up. 0.0.0.0 will not do, if a non-zero address
is
specifed it will be used, and if no address is specifed, the default is used. When the
link is
brought up, the request for a local ip address uses whatever address the interface is
using,
and this is where the trouble starts.
So, I suggest that if demand and ipcp-accept-local are both set, and no initial local
ip address
is specified, although the interface can be set up with the default address,
it would do no harm, and in my circumstances it would be helpful, to issue the initial
request
with 0.0.0.0 rather than the default ip address.
Is this reasonable? What's the process for getting this considered for inclusion?
