Hello, claudio987@xxxxxxxxx a écrit :
Hi, I have a problem. I have a Dlink router working with a linux based firmware This router uses an "outbound" nat and then is not possible to forwarding protocol 41 (protocol used to ipv6 tunnel) on an internal ip address of my lan. Now I ask you if is possible to change nat into bidirectional nat and than have the bossibility to set an entry in iptables to forward protocol 41
Assuming that the local IPv6 tunnel endpoint IPv4 address is 192.168.0.2 and the router's external interface is ppp0, try this :
# inbound destination NAT for IPv6 tunnel iptables -t nat -A PREROUTING -i ppp0 -p 41 -j DNAT --to 192.168.0.2 # inbound forwarding for IPv6 tunnel iptables -t filter -A FORWARD -i ppp0 -p 41 -d 192.168.0.2 -j ACCEPT
