How to set up a public NAT64 server?

[wtongze]

Hi guys, I currently have a VPS on Vultr and I want to run a public NAT64 server just like these guys did:

Jool NAT64 with BIND9 DNS64: set your DNS to 2001:67c:27e4:15::64 Jool NAT64 implementation is running in a virtual container on proxmox server. NAT64 routed prefix: 2001:67c:27e4:1064::/64 Quick ping6 test if up&running: ping6 2001:67c:27e4:1064::5bef:6015

>NAT64/DNS64 public test<

My server info: Ubuntu 16.04.3 Kernel 4.4.0-87-generic x86_64 IPv4: 45.77.184.213 IPv6: 2001:19f0:ac01:413::1/64

I have successfully installed jool and allowed IPv4 & IPv6 forwarding in sysctl.conf.

However, when I run these commands, I got an error on the ping6 command: root@vultr:~# /sbin/modprobe jool_siit pool6=2001:19f0:ac01:413::/96

root@vultr:~# ping6 2001:19f0:ac01:413::8.8.8.8

^C --- 2001:19f0:ac01:413::8.8.8.8 ping statistics --- 5 packets transmitted, 0 received, +3 errors, 100% packet loss, time 4015ms

Can anybody help me out? Do I need to setup something like DHCPv6 server?

Thanks

No, you don't need a DHCP server.

Jool can currently only translate traffic being forwarded. A ping that's sourced from the NAT64 is completely unaware of Jool.

This will be fixed when Jool 4 is released (the issue is #140). In the meantime, if you want Jool to translate its own machine's traffic, you can always enclose the NAT64 instance behind a virtual interface and translate through there: formal documentation, example. But most likely you don't need this, as a public NAT64 probably only really needs to translate forwarding traffic.

I'm assuming that's all there is to this issue. Feel free to reopen if you still have a problem.
