Hi,
Does someone know/uses a simple rule so that Kamailio only exchanges
traffic with machines in the dispatcher?
Best,

I use something like this on my boxes to keep them foreigners out:
if ( !ds_is_from_list() ) {
sl_send_reply("403","Your not in my dispatcher list");
}
Put this high up your config.
Cheers

New subject: Kamailio only allowing traffic with machines in the dispatcher.cfg?
Call ds_is_from_list([groupid]) when you receive a request. If it
returns true the request came from one of the members of the group (and
you can proceed), if it returns false you can reject it and drop the
request.

Peter

New subject: NAT single interface problems with Lan/Wan
I can get wan communication or lan communication working, but not both.
Setting this, allows wan communication, but then my lan tries to talk with my wan ip.
Single Interface: listen=udp:<lan_ip>:5060 advertise <nat_wan_ip>:5060
I see my wan_ip in the via header, so I assume that's causing the issues for my lan.
Using add_contact_alias for lan, with the advertise in my listen command, results in
[nathelper.c:835]: no need to add alias param
I've tried handle_ruri_alias();, but this doesn't seem to have an affect either.
Setting this, allows lan communication to work fine, but wan has issues.
Single Interface: listen=udp:<lan_ip>:5060
Where is the happy median?
Was going to try path, but I read this is not the correct work-around.
Any clues or hints, are greatly appreciated.

New subject: NAT single interface problems with Lan/Wan
Hi,
When kamailio is listening on more than one interface is is sometimes
necessary to use force_send_socket() to tell kamailio to use one socket
or the other. This means it will put the correct values into Via and
Record-Route headers. In the example below, I am choosing the socket
based on if the request has come from a dispatcher list, but any other
logic can be used.
#!substdef "!WAN_IP!x.x.x.x!g"
#!substdef "!LAN_IP!y.y.y.y!g"
route[RELAY]{
if (ds_is_from_list("CLUSTER_ID")) {
xlog("L_INFO", "Using WAN_IP for sending\n");
force_send_socket("WAN_IP":5060);
} else {
xlog("L_INFO", "Using LAN_IP for sending\n");
force_send_socket("LAN_IP":5060);
}
t_relay();
}
Regards,
Hugh
