Hi I'm using "Tomato Firmware v1.28.4493 MIPSR2-Toastman-VLAN-RT K26 USB VPN" and everything has been working wonderfully for the past 6 months. I've begun to use IPv6 more and more, and am now interested in getting a stateful firewall working. However, when I try, I get an error about an invalid argument being given to ip6tables. Here is what I'm trying to do with a 6in4 tunnel: Code: ip6tables -A INPUT -i v6in4 -m state --state ESTABLISHED,RELATED -j ACCEPT Any help would be greatly appreciated. Thanks for the great firmware!
I didn't mention it in my last post, but I had been looking for a kernel module. Sure enough, as soon as I added the module to my kernel, my stateful firewall was up and running. I made it permanent by adding the line below to my IPv6 wanup firewall script. Here's the command for those who are looking to do this in the future: Code: modprobe nf_conntrack_ipv6.ko
