Title: DHCP Gateway On VLAN override default LAN
Edited by Sogi White at 2025-2-10 11:32

Hi,
I have problems here, my vlan gateway overrides with default LAN gateway. I think this is kind of bug with the firmware. Or you have solution for this?
In my case, My default LAN is 192.168.110.0/24 with gateway 192.168.110.1
I setup vLAN10 which the IP Subnet is 192.168.120.0/24 with gateway 192.168.120.1.
hovewer, if I connect my wired clients to local LAN ports, it's get the default LAN IP address, but with the vLAN 10 gateway! how to solve this? I want to segmenting my networks.
I'm using RG-EG210G-P-v3
Thanks.

Hello there,

I think I made mistake here, and I don't know what gateway is specific use in the dhcp option is. But, after I remove the gateway address from that, it's working as expected.

Maybe, R&D team should give a clue to what's the use of it. Or, should they add more specific dhcp setup, like custom gateway address right? so we can more flexible to setup the networks.

Dear
It is the IP address of the default gateway or default route that the DHCP server assigns to clients. The default gateway is the next hop address used by a client to send data packets to an external network. It is responsible for forwarding the data packets to the target network.

You can check the following guide for more details.

Hi,
What I'm thinking is, how to add custom gateway for each vlan instead of automatically generated by default like 192.168.x.1?

Hi sir,

By default, the gateway is used as the address pool server  to  allocate  addresses  to  access  clients.If  an  access  switch  is  available  in  this  networking,  you  can select this switch as the address pool server.

Best regards,
Steve
specify  the  address  pool  server  for  access  clients  in  this  VLAN,  and
determine whether to create a new DHCP address pool. By default, the gateway is used as the address pool
server  to  allocate  addresses  to  access  clients.
If  an  access  switch  is  available  in  this  networking,  you  can
select this switch as the address pool server.
