[SR-Users] Diameter sorce/destination port

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
