I've noticed alot lately when reviewing Upnp forwards that Teredo consumes alot of nvram space and does not close the forward when a client computer on the LAN disconnects.
I did some reading and found some pretty interesting stuff, but not anything specifically related to DD-WRT's netfilter.
I currently have two options, and one is very impractical. Disable uPnP on the router or require all clients to disable the IPv6 stack in Windows Vista and Windows 7 PC's.
The other option (the one I'm asking about) is using iptables to block access to all clients on the LAN.
Currently, this is the best ruleset I could find searching the web:
Does anyone else have experience with this?
Any help, suggestions, negative remarks are much welcomed
