      Is there no way to forward a custom IP protocol number?

      I am tunneling IPv6 in IPv4 and would like to forward that protocol number (41) internally into another firewall.

      I could have sworn this worked in earlier versions.  I am now on 2.1.1

      Can this be done still?  The option doesn't seem to be in the WebUI.

      If it helps…here is how it's done in IPtables/DDWRT

      iptables -t nat -A PREROUTING -i eth0 -p ipv6 -j DNAT --to-destination 192.168.1.10
      iptables -A FORWARD -d 192.168.1.10 -p ipv6 -j ACCEPT

      Thanks,

        Uhm… System - Advanced - Networking - IPv6 over IPv4 Tunneling

        Enter the IP there. Done.
