Additional LAN IPs

I intend to deploy VOIP phones, network printers, workstations, and wireless access points. but running low on available IP address.

my current network is
192.168.1.0 / subnet 255.255.255.0 (or 192.168.1.0/24). how can i obtain more IPs for this intended purpose? i need communication to exist between all IPs on the LAN.

KR,

Stephen

  • Hello Stephen,

    Thank you for contacting the Sophos Community!

    As mentioned by System Administrator, if you want to increase the number of IPs you need to move the Mask, however, if this isn’t a possibility, you can try using VLANs You can configure a VLAN to use 192.168.2.0/24 for example. For the devices to communicate you would need some routing and a switch that supports VLANs.

    Try configuring VoIP phones in their own VLAN, and Workstation in their own VLAN and AP in their own VLAN, basically segment your network by devices. 

    As a recommendation try to stay away from using 192.168.1.0 and 192.168.0.0 subnets in business environments as this can cause you issues in the future if you try to deploy SSL VPN or IPsec tunnels with home users as the subnets mentioned, as used by 99% of the home users.

    Addition to Emmanuel post, you can also add the alias interface with different subnet and can create LAN to LAN firewall rule to allow access between them:
