I've got a "specific" "unsupported" home setup : I've configured pfSense with IPv6 using ndproxy. ;)

Because my ISP only gives me a /64, because I don't want my LAN to be accessible. Because.

But I don't think that's my issue. So today I started the 2.4.5 upgrade and started with my backup pFsense (configured in HA, yes). And I got issues. At first I thought the upgrade freezed, but running the upgrade in an SSH shell, I got different kind of errors :

• painfully slow downloads of packages
• connections reset by peer
• and others I forgot

pkg downloads are actually working, but at a very very very limited download speed.

Off course it can be my setup that's bad (ndproxy), but I'm not asking for help as I discovered I could "pfSense-upgrade -4d" to do an IPv4-only upgrade : I'm just posting to report this weird v6-only issue, or to ask others if they would face that kind of issue ? I'm not facing v6 issues on my LAN... because I haven't configured v6 on the lan yet.

My DSL is only 3mbits, but I'm facing 1kbps like speeds for some packages (not all ?) using default hence IPv6.
I ran a v4 upgrade on my secondary : it finished in minutes
I'm now upgrading my primary : it's "hanging" on :

[66/142] Fetching pfSense-base-2.4.5_1.txz: 

Still I'm receiving ipv6 packets according to tcpdump, but at a very low rate :

[2.4.4-RELEASE][root@pfSense.lan]/root: time tcpdump --dont-verify-checksums -vvi vtnet1.11 'ip6 and ( port 443 or port 80 )' -w dump.pcap
tcpdump: listening on vtnet1.11, link-type EN10MB (Ethernet), capture size 262144 bytes
^C55 packets captured
150 packets received by filter
0 packets dropped by kernel
0.016u 0.000s 0:10.22 0.0%      924+1552k 0+0io 0pf+0w

It can be many things in the IPv6 path from my pfSenses to my ISP (French "free") or anything else - just wondering if I'm alone ;)

I haven't tried yet to run any kind of ipv6 iperf tests - I'm behind a damn slow 3mbits line :/

Regards

(will have to run a v4 update :/)
