作为Google支持Google Compute Engine上的原生IPv6之前的一个障碍,我想配置一个6in4(IP协议41)隧道.
我添加了防火墙规则以允许我的VM网络上的协议41:
Name Source tag / IP range Allowed protocols / ports Target tags
allow-6in4 216.66.xxx.xxx 41 Apply to all targets
并配置隧道/etc/network/interfaces:
auto 6in4
iface 6in4 inet6 v4tunnel
address 2001:470:xxxx:xxxx::2
netmask 64
endpoint 216.66.xxx.xxx
gateway 2001:470:xxxx:xxxx::1
ttl 64
up ip link set mtu 1280 dev $IFACE
并且ping6 2001:470:xxxx:xxxx::1验证了6in4流量是出站的:
$ sudo tcpdump -pni eth0 host 216.66.xxx.xxx
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening …
