  • Hi Zyxel_Cooldia, no work with sip ALG, ALG replace public ip in sip message, server no accept this. My sip server needs to know port and ip source to accept sip messages, I configured trunk in my server (Ip and Port) and only this trunk is enable to accept message. Trunk use Ip authentication no User authentication Alex

  • Hi PeterUK, it is strange, I can't have 2 different external IPs with the same port on 2 wan inbound with nat 1: 1 on the same server without the external port source changing? Trunk VoiP need trust IP and PORT external, Zywall change external source port dynamically. Alex
