Hello,
I'm doing some work in my home lab, my goal is to have as few devices as possible powered on at all times. To achieve this, I would ideally like my router to handle my DHCP and DNS. Part of what I'm working with in my lab requires both option 66 and option 67 configured as scope options. I can't use the router/modem provided by my ISP as it does not support this feature, so I dusted off my old Asus RT-N13U with the sole purpose of using it for DHCP,DNS, and IP reservations the only settings which are not working are option 66 and option 67.
Everything My config is below:
Router Model: Asus RT-N13U
Firmware: DD-WRT v3.0-r27378 (06/19/15) std
Use DNSMasq for DHCP (ON)
Use DNSMasq for DNS (ON)
Services Services DNSMasq
DNSMasq (Enable)
Local DNS (Enable)
No DNS Rebind (Enable)
Query DNS in Strict Order (Enable)
Add Requestor MAC to DNS Query (Disable)
You have a realy old version and a realy particular setup.
It looks like this is a WAP (Wireles Acces Point) but then running a DHCP/DNS server.
Not impossible but strange
I don't want to use this for wireless clients at all, wireless network mode is set to disabled. Should I set the wireless mode to something else or does it matter?
I am pretty sure that the tftp compiler option is not set by default (and I assume that tftp is mandatory for pxe)
You should be able to check with :
dnsmasq -v
I am afraid it will show no-TFTP
(The last time I compiled with TFTP it made my DNSMasq crash )
Sorry I'm really new to this and I'm not sure where I run this command from. You want me to telnet into the router and run dnsmasq -v by itself? When I do that I get no output.
