    So would this from WAN to LAN1 or LAN1 to WAN? do you only want SIP work and nothing else?

    IP and port your wanting to allow and with SIP ALG enabled?

    Hi @jak67429  

    In default configuration, policy control rule blocked all of traffic from Internet except VPN/GRE/VRRP services.

    If you would like to allow traffic from external SIP server to Internal SIP client. You can add policy control rule for your SIP server first.

    e.g From: WAN, To: LAN1, Source: YourSIPServerIP, Destination: any, Action: Allow.
