Anybody here got mad skills with pf, NAT and IPv6 on #FreeBSD?
I have my jails on an extra loopback device (lo1) and have rules like this in my pf.conf to get traffic to them:
rdr pass on $ext_if proto tcp to port 80 -> 10.101.1.2 port 80
This is what I suspect to be the cause behind the jails not being reachable over IPv6.
First of all – is that really the case?
And secondly, how do I add IPv6 support to that?
10.101.1.0/24 being the subnet used for the jails on lo1 in case that wasn't clear.
I already tried adding the same rule with an IPv6 address, but that doesn't fix my issue:
rdr pass on $ext_if proto tcp to port 80 -> fe80::10.101.1.2%lo1 port 80
@phryk isn't tcp6 instead of tcp what you need? I don't have IPv6 anywhere, so I can't test it
@meka Weird. I thought the same but have no idea where I got that from because pfctl -nf /etc/pf.conf gave me a syntax error with that…
@meka /etc/pf.conf:7: unknown protocol tcp6
@phryk based on https://bash.cyberciti.biz/firewall/pf-ipv6-ipv4-firewall-for-freebsd-openbsd-netbsd/ it's inet6 and tcp
@meka Thanks, lemme try that. :)
@meka Mhh, no syntax error, but no working NAT either, it seems…
@meka Oh, the jails don't even get v6 addresses assigned, even tho I specified ip6.addr… >:/
@meka On second try (after finally getting nmap going on a different host where I have working IPv6), I'm seeing that v6 NAT *does* work for SSH so I'm assuming this isn't the NAT after all but rather the nginx setup…
Thought it'd do v6 by default…
@meka Wait, I'm stupid, this is the hosts ssh, got nothing to do with the jails. m)
