    Hi, I have ATT fiber using the BGW210 and have the Asus AC86U connected to it using the Ethernet port. Asus Merlin Firmware Version:382.1_2
    For some reason it wont connect to a UDP file only to TCP
    Support told me is mostly something with the ATT modem.

    I disable most of the firewall setting on the ATT modem.
    Firewall setting
    Packet Filter Off
    IP Passthrough Off
    NAT Default Server Off
    Firewall Advanced On

    Here is the advance settings:
    Drop packets with invalid source or destination IP address - Off
    Protect against port scan - Off
    Drop packets with unknown ether types - Off
    Drop packets with invalid TCP flags - Off
    Drop incoming ICMP Echo requests to LAN - Off
    Drop incoming ICMP Echo requests to Device LAN Address - Off
    Drop incoming ICMP Echo requests to Device WAN Address - Off
    Suppress ICMP error responses - Off
    Flood Limit - On
    Flood rate limit
    e.g. 4
    Flood burst limit
    e.g. 8
    Flood limit ICMP enable - On
    Flood limit UDP enable - On
    Flood limit TCP enable - On
    Flood limit TCP SYN-cookie - On
    Neighbor Discovery Attack protection - Off
    ESP Header Forwarding - On
    Authentication Header Forwarding - On
    Reflexive ACL - Off
    ESP ALG - Off
    SIP ALG - Off

    On the custom configuration I have the supplied setting from NordVPN

    remote-cert-tls server
    remote-random
    nobind
    tun-mtu 1500
    tun-mtu-extra 32
    mssfix 1450
    persist-key
    persist-tun
    ping-timer-rem
    reneg-sec 0
    # log /tmp/vpn.log


    What else could I try?

    Thanks.

    Not sure I can follow. Ex.. Are you trying to use the built in VPN Client to connect to a VPN service with UDP?

    Why not run the attempt to connect then go to the router system log/general log and copy all the lines from the moment you activated the VPN Client? Paste them here and perhaps someone can offer some input.
