When I enable DMZ in the router, the DNS server/relay stops working.
Verizon FiOS: 75/35
Firmware Version: 40.20.7
Model Name: MI424WR-GEN3I
Hardware Version: I
DMZ disabled:
>nslookup www.microsoft.com Server: Wireless_Broadband_Router.home Address: 192.168.1.1 Non-authoritative answer: Name: lb1.www.ms.akadns.net Address: 64.4.11.42 Aliases: www.microsoft.com toggle.www.ms.akadns.net g.www.ms.akadns.net
DMZ enabled: 192.168.1.24
>nslookup www.microsoft.com Server: Wireless_Broadband_Router.home Address: 192.168.1.1 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** Request to Wireless_Broadband_Router.home timed-out
Totally reproducible, clear DMZ checkbox and save, and DNS works, check checkbox and save, and DNS stops working, repeat.
There is nothing interesting in the logs.
Any ideas?
