We have a router with NAT enabled on our edge. The NAT inside is 10.0.0.0/24. Now, we're running out IP blocks and we wish to change this to 10.0.0.0/22. We can do this quickly on the NAT router. But for the host devices, do we need to replace their subnet mask as well and use /22?
We have a mix of DHCP and Static IP address users here. My initial thought is we can skip them from changing the Subnet Mask and still use /24 since the default gateway is still 10.0.0.1. Is this a correct assumption? Thanks.
