DHCP Wrongly Assigned IP address for different interface

Current network having two interface with different subnet. Both interface connected to same switch without VLAN.

Port 1: 192.168.0.1/24

Port 6:192.168.100.1/23

DHCP Server

Aruba Access Point was placed in 192.168.100.x network, and having static IP Address 192.168.100.1-10, with gateway 192.168.100.1/23.

However user that connected to the access point are assigned with 192.168.0.x IP address.

Is there any way to allow user that connected with wireless access point to request IP Address only from .100 network, and user connected with LAN cable from switch request IP address only from .0 network?

XG210 (SFOS 17.5.15 MR-15)

  • Hi Sze Xian Yam,

    you are running two networks on the same layer 2 infrastructure. Doing so is not what you should do in network design. 

    1) You could define two VLANs on the switch (if you are able to do so). Connect everything that belogs to LAN to VLAN 1. Everything that belongs to WiFi to VLAN 2.
    You will need also to connect the corresponding interfaces to this VLANs.
    Or -  you can use tagged VLANs 1+2 on the firewall and on the uplink of the switch.

    2) You could use the same network for WiFi an LAN. If necessary use /23 instead of two /24 in order to have enough free IPs.
