I am having to rebuild my site lan and wifi setup due to device failure and wish to get advice please on a basic principle as I wish to depart from what I have done in the past.
I prefer to set fixed IPs to wifi routers and bridge devices so I may easily access them. Must these addresses be in the same subnet as that of the dhcp server which defines the subnet?
For example I have a firewall/router which is also acting as dhcp server. This is connected by lan to a dedicated wifi bridge (using WDS). The remote bridge device is connected by copper to a wifi router which is accessed by various clients.
The two bridge devices and wifi router all have fixed IPs but I only need to access them to change settings. Other than facilitating this access, is there any reason why the subnet being served by the dhcp server must be the same as the device addresses. I ask because I want to set up the devices and then plug the end into a different router which will also act as dhcp server but will use a different subnet.
Hope this is clear and sorry if question is dumb but I have conflicting advice from hardware suppliers.
