Cisco RV220W - local name resolution

Level 1

Hi - I have an out of the box configured RV220W and was wondering if it supports local DNS resoltuion for DHCP addresses it issues. I have a few reservations and a custon search domain configured ('local') but it will not resolve a name fromt the terminal using the search domain (see below):

It resolves freenas but not freenas.local.

macbookair:~ brantwinter$ dig freenas

; <<>> DiG 9.8.1-P1 <<>> freenas

;; global options: +cmd

Should this router be able to resolve names to IP addresses it issues ? Any help appreciated.

The router is not a DNS server. You may set as a DNS proxy.

When enabled, the RV220W then acts as a proxy for all DNS requests and communicates with the ISP's DNS servers. When disabled, all DHCP clients receive the DNS IP addresses of the ISP.

I am not sure how many 'SOHO' high end routers you have played with but a lot of them will resolve names on the local search domain that they have distributed via DHCP. The cheap Asus RT-N16 running Tomato formware that this replaced did the job just fine.

How many SOHO offices run their own DNS server ?

Installed dnsmasq on a local file server to run as a DNS server and all is fine now.

*edit:- The RV220W actually runs DNSMASQ 2.45 (for the poster above, this IS a DNS server as well as a DNS proxy etc). This software DOES allow the ability to act as a DHCP server (that is probably what Cisco is using here) and DOES allow the feature to resolve names to IP's for addresses it has handed out. Why on earth does Cisco not fix this ?

Some very strange things observed. If you do not have DNS Proxy ticked nothign works - even if I am running an external DNS server. I'll give this thing a week - if it is still annoying me it's going back to work and someone else can have it !
