I am wondering if anyone can help with this ip6tables issue. I am running DD-WRT on the R7000 and trying to block all connections from my network to one or more hosts. For example, suppose I hate Yahoo! and don't want anything connecting to www.yahoo.com. The following iptables command seems to work fine for IPv4 traffic:
The above ip6tables command results in the error message:
ip6tables v1.3.7: host/network `www.yahoo.com' not found
Both iptables and ip6tables seem to work fine if I use nslookup and specify the IPv4 and IPv6 addresses respectively instead of a hostname. Is there any way to get ip6tables to resolve a hostname like iptables does?
(Edited to correct/clarify that I mean "host" name and not "domain" name.)
Turns out after updating to build 29165, the router fails to get an IPv6 address from my ISP (TWC) using DHCPv6 w/ Prefix Delegation. I've also tried build 29200. Upon reverting back to 27775, the DHCPv6 works again.
So now I have to figure that one out because ip6tables does me no good if DHCPv6 is failing.

Just noticed that I somehow managed to post this under ARM/PPC when I'm actually using a Broadcom device. So I'll make any further posts under Broadcom in case my issues with the latest firmware builds is specific to the R7000. Thanks!
