I would suggest some modifications to the firmware RV0xx devices because it is deficient in some characteristics:
1 - In Website Blocking Keywords and Forbidden Domains, there could be an exception list of LAN hosts that were not affected by these blocked sites.
In the Netgear firewalls this possibility exists.
E.G 192.168.1.2 can access youtube.com
192.168.1.3 can not access youtube.com
2 - I also have problems with the WAN port using PPPoE dialer, when using the dialer problems have several sites not open, I think it's a failure of the DNS service of the router's internal router.
I contacted support CISCO and asked me to downgrade the firmware, now use Release 4.2.1.02.
This happens only on ports using PPPoE.
3 - The device accepts not add domains using wildcard eg: *. Microsoft.com or * yahoo *. *
I appreciate the attention of staff development and support of cisco
