In a valid subnet mask network part is represented with "1" from left side followed and ended by host part "0" - 11111111.11111111.11111111.00000000 (binary form), 255.255.255.0 (dotted-decimal form) or simply "/24" (where 24 represents that subnet network part is 24 bits long). Subnet calculator allows calculation for 255.255.255.254. Host Bits Solved: Multiple routers and subnets - can't access across The router now has a route between Subnet 1 (192.168.1.*) and Subnet 2 (192.168.2.*). You should be able to ping systems on Subnet 1 from 2, and ping systems on Subnet 2 from 1. You should not be able to access any systems, though -- the firewall is still blocking all but ping traffic from Subnet 1 to Subnet 2. IP Subnet Calculator
If that's all, the most simple and low-know-how way would be using the existing network as a "by-pass" network, add a WiFi router in NAT mode, plus a network switch if more Ethernet ports are required, and configure that LAN on a different IPv4 subnet, Just adding a VLAN capable switch, even with L3 routing, won't help much in my opinion.

Understanding TCP/IP addressing and subnetting basics Dec 19, 2019 What is a Subnet Mask Address and How to Find Yours So, a subnet is used to enable a collection of devices to connect to the Internet with a single IP address through the use of a router (like you have at home or in your office) and in this way a lot more than three billion devices can have access to the Internet. This is what was explained above with 1 public address for your whole network. VPCs and subnets - Amazon Virtual Private Cloud The CIDR block of a subnet can be the same as the CIDR block for the VPC (for a single subnet in the VPC), or a subset of the CIDR block for the VPC (for multiple subnets). The allowed block size is between a /28 netmask and /16 netmask. If you create more than one subnet in a VPC, the CIDR blocks of the subnets cannot overlap. IP Tutorial: Subnet Mask and Subnetting
