Hi,
This is my case.
We have a rang of WAN IPs (Ex: 192.168.0.96-255.255.255.248)
If I configure WAN1 or WAN2 or WAN sub-interface with the IP 192.168.0.98 this ip not work, I can't ping internali this IP, but if I configure other IP address range (97,99-101) my USG work well.

Some one has ideia about this?

    Hi @RaphaelOliveira,

    For some ISP, some IP addresses are used for access link only, not for data link.

    When you configure 192.168.0.98 in wan1, use the following command on web console to check the ping result.

    Router# ping 8.8.8.8 interface wan1

    Before entering the command, capture packets on wan1 interface and filter by icmp.
