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.
