I want my clients to use a /19 subnet but want them divided along 4 /21 subnets:
- /21 for servers, printers and so on
- /21 for LAN clients
- /21 for WLAN clients
- /21 vor VPN clients
The subnets for servers, LAN and WLAN clients shall be served by DHCP running on a server with multiple VLAN interfaces in each segment. Also, a router is configured with VLAN interfaces in each segment. My concern is if I need to configure the interfaces each as /19 or /21. Or do I have something completely misconceptualized?
Edit in response to Ron Maupin:
- 1 EdgeRouter PoE
- 1 Cisco SG300-52
- 1 TP-Link TL-SG2452
- 2 TP-Link TL-SG3424P
- about 2 dozens of TP-Link TL-SG3210 in different rooms
- about a dozen Ubiquity access points spread over the floor
The EdgeRouter PoE can provide DHCP but not dynamic DNS, so there's a server doing both. A single /24 subnet got to small, thus I have to redesign the network during productive use. One department working with credit card information and stuff like that needs its own seperate network, thus they have their own VLAN. Currently, we have our regular office VLAN (default 1), a guest VLAN (20), a VLAN for WiFi (50) and the seperated VLAN (100). Our dedicated server serves DHCP and DNS for VLANs 1 and 50 but I want it to do the others, too.
