I was trying to set a DHCP pool with 127.16.0.0/16 with RV220W, however, RV220W UI can't save it. It displays "IP Address Range -"
Firmware 1.0.3.5 (just downloaded from cisco)
Browser: IE 8 and Chrome
Step to reproduce: (it is 100% reproducible)
1. login into RV220W admin web
2. Create a VLAN, id 201
3. Go to "Multiple VLAN subnets", select the VLAN, click edit
4. Enter following info:
IP Address: 172.16.0.1
Subnet Mask: 255.255.0.0
DHCP Mode: DHCP Server
Domain Name: Cisco
Starting IP Address: 172.16.2.100
Ending IP Address: 172.16.10.254
Primary DNS Server: 172.16.0.1
Leave rest of settings with default value.
DNS proxy is enabled
5. Press Save button. The UI shows text "IP Address Range -".
Screenshot is attached (RV220W-DHCP-IP-POOL-ERROR.png)
Expected result: RV220W shall save the setting and make use of 172.16.0.0 subnet in IP pool.
By the way, the error message "IP Address Range -" seems incomplete
I tried same setting on netgear FVS318N (very similar settings to RV220W), it accepts 172.16.0.0/16 as DHCP IP pool and works.
RV220W has great feature set meets my needs. Its UI is slow and sometime dashboard freezes, which I can live with comparing to features. But DHCP server IP pool can't be class B is huge limitation to me. Any firmware could fix it?

Hello Mkkk,
What you are getting here (IP Address Range) is a message showing that your address pool is too large. No matter what class you are choosing to use the router will only allow a pool of approx 254 addresses per subnet. Your address pool range will have to end at 172.16.3.98 or there about.
Thank You,
