It's actually an educated guess that this could be related to wt_timer,
but I don't know what else it could be.
what happens is that when transaction is active and tm is handling the
replies, they are forwarded using the same socket where the request was
received (iirc).
However, the transaction is gone so the reply is sent stateless and the
default rule of stateless forwarding for selecting the local socket is
to use the same socket where the message was received (in this case is
the reply is received on loopback interface). Try either to use mhomed
parameter or force the right send socket by hand (force_send_socket(...)
or $fs=...) when there is no active transaction for replies (use
t_check_trans()).
Actually I do a force_send_socket in my onreply_routes, but the
onreply_routes to be used are chosen during request handling. I don't
have a default reply route though, which I guess must be used in this
case, because information about which onreply_route to use is lost after
wt_timer, right?
yes, a default onreply route has to be used.
Roughly outlined, this is what I have now. I don't use mhomed, but
rather set the sockets manually:
route[REQUEST]
{
if(request from outside) {
force_send_socket(localhost);
t_on_reply("REPLY_FROM_INSIDE");
}
else { # request from inside
force_send_socket(public interface);
t_on_reply("REPLY_FROM_OUTSIDE");
}
# relay to proper destination
}
onreply_route[REPLY_FROM_INSIDE]
{
force_send_socket(public interface);
}
onreply_route[REPLY_FROM_OUTSIDE]
{
force_send_socket(localhost);
}
And this is what I'd need to add if I got you right:
# the default reply route used when transaction is already gone
onreply_route
{
if(reply from inside)
force_send_socket(localhost);
else
force_send_socket(public interface);
}
Does it look like a plan?
You should check first with t_check_trans() to see if transaction is
gone. the default onreply route is called for all replies, no matter the
transaction exists or not. Reading the logic, I find it opposite, if the
reply comes from inside, you want to send it outside, via public
interface, or?
Cheers,
Daniel
