Port Forward a custom IP Proto number?
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
Uhm… System - Advanced - Networking - IPv6 over IPv4 Tunneling
Enter the IP there. Done.
