Title: VLAN configuration
Hello, I successfully introduced the RG-WALL into my Topology but it eliminated the existing router as well as the core switch. Now it's handling everything as I deployed it in routing mode. How can I replicate the existing vlan configs on the previous router sub-interfaces that we going to the core switch?
New Topology;
ISP > RG-WALL_FW > Access SW

Previous Topology;
ISP > Router(with vlan configured on the sub-interfaces) > Core SW

Currently, only the admin network is running smoothly. Here's the setup;
WAN port on the FW is port 4
LAN port on the FW is port 2 (static IP add configured as my admin network is static.

The challenge is onboarding the guest and cctv on the FW. I attempted configuring the exact configs from the previous router(vlan 2 for guest, IP add 192.168.1.0 255.255.255.0 and enabled dhcp service on port 3 of the FW, (the same for the CCTV(vlan 4, ip add: 192.168.254.1) but the guest access points failed to acknowledge( and the cctvs go off) yet the admin network works perfectly. Kindly assist and help with an explanation.

I look forward to hearing from you.

Dear Customer,
Ruijie RG-WALL also supports sub interfaces to terminate different vlans. One physical interface supports multiple sub interfaces to terminate multiple vlans as follows.

Could you check if it can meet your requirement?

I already did that but it's not working. Does it mean that the interface I decide to use for the sub-interface doesn't need to have an IP address assigned?

Dear Customer,
Generally while using sub interface, the vlan subnet's gateway is sub interface IP, so you need to assign one IP address to the sub interface.
