Hi All,

I am trying to use Cx (Diameter) interface via TCP  towards our HSS
according to Carsten Bock example.

However kamailio client obtain TCP RST from HSS because a kamailio source
port is different than port where kamailio is listen. I do not know if this
is Diameter/Cx requirement or not. I did not find it in specifications. Is
there any way how to ensure that kamailio use same port number for source
and destination (3869)?.


<?xml version="1.0" encoding="UTF-8"?>
<DiameterPeer
        FQDN="...3gppnetwork.org"
        Realm="...3gppnetwork.org"
        Vendor_Id="10415"
        Product_Name="CDiameterPeer"
        AcceptUnknownPeers="1"
        DropUnknownOnDisconnect="1"
        Tc="30"
        Workers="4"
        QueueLength="8"
        TransactionTimeout="5"
        SessionsHashSize="128"
        DefaultAuthSessionTimeout="3600"
        MaxAuthSessionTimeout="3600"
>
        <Peer FQDN="hss....3gppnetwork.org" Realm=".3gppnetwork.org"
port="3868"/>

        <Acceptor port="3869" />

        <Auth id="16777216" vendor="10415"/> <!--3GPP CxDX -->

        <Realm name="....3gppnetwork.org">
                <Route FQDN="hss...3gppnetwork.org" metric="10"/>
        </Realm>

        <DefaultRoute FQDN="hss.....3gppnetwork.org" metric="10"/>
</DiameterPeer>

Thanks
Peter
