Sorry, I Misunderstand your answer before.
I try to add a bridge wifi, add the vlan 123 in the option, but I can not search the wifi on mobile, also I can not see enable broadcase like tunnel mode, do the bridge mode only use to enable the wifi?
Yes, It can use if it is used as independent subnet, but the other branch need to limited the subnet in VPN. the vlan 123 is a one of internal network with wifi and phycal cable lan port. Sorry need to use in vlan.
I confirmed the other branch is using the tunnel mode but can use the vlan IP, but they do not provided the config to me. What other prossible setting can make a tunnel mode ssid in vlan?
