IPv6 incoming not working.

[jtl]

Hi

New to IPv6. I have Telus internet. Recently got IPv6 working with my new pfSense box. I can use the IPv6 internet normally, browse to sites, ping things, but anything incoming seems to be blocked and I would like to allow ICMP incoming, as well as other hosted services.

I am testing from a remote DigitalOcean box with IPv6 and Nmap for port scanning. Just using netcat to listen to ports, etc.

Running pfSense 2.4.0.b.20161118.1539.

Here is test-ipv6.com results.

Here are my firewall rules for WAN and LAN

As I test I used```
nc -6 -l 8088

Here's an example

[root@router ~]# tcpdump -i em4 port 8088
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on em4, link-type EN10MB (Ethernet), capture size 262144 bytes

(Sorry for the somewhat abrupt and ad-hoc writeup of this, have a headache)

Hosting services to the internet works just as IPv4 but no NATting to a private space.
You specify a LAN host with an IPv6 IP and open the WAN port for that destination.

I know, but first I'm trying to get ICMPv6 pings working, as a sanity test.

Uh huh, so you allow ICMPv6 only and are wondering why you cannot reach some port 8088 inside?

Put a rule in Floating anywhere anywhere (input/output) for ICMPv6

[doktornotor]

Floating or not won't matter, a rule for ICMPv6 won't ever match his internal machine listening on port 8088.

@jtl:

As I test I used```
nc -6 -l 8088

I created another rule for port 8088 and that works. Here's a bit of a cluttered screenshot showing it. Left window is remote server, and right is netcat.

Need to read up more on IPv6 sometime.
