  • Ticket #864 – Description

    v1 v7  
     1== Handle But in NAT Router === 
     2 
    13Some firewall such as Microsoft Forefront Threat Management Gateway may leave rport parameter with wrong port number, causing us to update our registration Contact with wrong URI. 
    24

    1012Probably we don't need to do registration update when only the port number changes. 
     13 
     14 
     15== Always Update Via Address === 
     16 
     17While the Contact address is updated by acc_check_nat_addr() function, the Via (i.e. transport address) is only updated if the transport is UDP and STUN is enabled. 
     18 
     19For TCP/TLS, this is a bug, as the Via address should always be updated. 
     20 
     21For UDP, probably it's better to always update it too, as some server will still think that we're behind NAT (while probably true, we want the server to think otherwise).
