So I did a little more digging and stumbled upon;
2010/11/09 01:24:11.791 2 Toolkit.cxx(292) Default
IP=10.10.10.36
Digging further into Toolkit.cxx in function
Toolkit::RouteTable::InitTable();
// Get all the interface addresses available
std::vector<PIPSocket::Address> home;
PString foo = Toolkit::Instance()->GetGKHome(home);
if (!home.empty() && home.size() > 1) {
// Set default IP to Bind IP, if given.
PString bind = GkConfig()->GetString("Bind", "");
if (!bind) {
defAddr = bind;
} else {
defAddr = home[0];
}
}
This code + my configuration causes my Bind= to be ignored, specifically
I'm wondering what;
if (!home.empty() && home.size() > 1) {
is trying to match. If I remove this "if" from the code, my Bind
configuration is accepted and the above "Default IP" now returns
correctly, and my calls also now work as the ACF packet now has the
correct IP address for the endpoint to talk to.
Thanks
