Since I have used two peplink 210 and set the high availability in the group ID 1.But the Wan 1 of Peplink 210 cannot ping the internet gateway. The wan 2 is OK in the same setting.
When i have changed the group ID to 80. The Wan 1 and Wan 2 will return normal.
We would like to know what are the different of the high availability group 1 with others group number.
