I disabled those 2 rules....

Then ran the IPv6-TEST again -- and now I am back to 17/20:

@bearhntr you can allow icmp.. but your not going to get the PTR, and if no ptr hostname not going to resolve either. I would prob set it to just echo requests.. but you do you.

bearhntr

@johnpoz

Thank You -- Done // we back to 19/20

johnpoz

@bearhntr I see you hid your ipv4 this time, but its clear as day right there in your hostname for your IPv4, via the PTR - heheh

@johnpoz

Yeup. I really do not care so much about the v4 IP address - - it will change by mid-day Saturday. <Grin>

I really want to grasp this IPv6 stuff. I would love to move more and more stuff in that direction. I have a few devices in my home which will not do IPv6 and the mfg. says they have no plans of supporting it anytime soon.

First time I enabled ICMP for IPv6 and getting 20 of 20. Feels so good.

But in the end, never needed that ICMP for anything.

Why to be honest? Can you name 1 resource that requires IPv6 that you want/need to access.. I agree that it is the future, and applaud your desire to learn it and play with, and sure even enable it.. But sorry no matter how much say jknott wants it to be now, ipv6 as the mainstream protocol is decades away..

Now - if some major players would push, it could be much sooner.. My isp has zero plans to support it, and its not even on their roadmap.. They just got bought by RCN, so maybe that will change..

I have it running on my network in a limited capacity - I can click a button and my pc has ipv6, as you saw for example in my test. But most of the time ipv6 is off.. I just don't really have any need or desire to run it as main protocol.. And it for sure makes limiting what can be done or not done through the firewall more difficult.. Clients love to have loads and loads of different IPv6 addresses they use for outgoing - so its more difficult to say for example my iphone IP can talk to my plex server IP from the specific wifi vlan.. With ipv4 I just assign it a dhcp reservation - and it always has the same IPv4 I can work with.

Not saying can't be done - its just more difficult, for why? Other than it is the "future" I have seen no actual need for it on my network, or for talking to the public internet.. My printer not having IPv6 support means nothing, who cares.. My smart lightbulb or some other iot device - again zero need or want for them to support ipv6.. For 1 it just makes it more difficult to manage..

So yeah learn and play and discover - happy to help in any way I can for sure.. But in the big picture.. The future is not right around the corner - you got plenty of play time heheh..

If you want some fun learning - go get sage cert over at hurricane electric, its free.. Fun to do, will help you learn different stuff about IPv6. And you get a free tshirt when you reach sage level.. Mine is getting a bit ragged - but I still sport it now and then..

I agree. For some masochistic reason I decided to see if I could figure this out. After I did, I asked myself, “Ok, that’s working. Good job. Now what functionality did it give me?”. I then proceeded to set IPV6 to none for WAN. There is so much more learning I can do that has a real return on investment.

I did not know there were t-shirts to earn. That changes everything.

Very true! I have been wanting to leverage IPv6 at work since 2010-11ish time frame.. Nothing ;) And I work for a major player.. I just recently helped them get /32 from Arin for use in a project..

I will for sure be retired before ipv6 becomes real mainstream protocol.. Sad but that is the way it is..

Bob.Dig

The US has plenty of IPv4 addresses. In other parts of the world this is not the case. For instance in Germany there is more and more IPv4 CG NAT and/or DS-Lite (Dual Stack Lite). So if you want to host something at home, you have to use IPv6... but also every major cellphone provider here supports it ootb, so it is doable, although it sucks big time.

I have to assume they are still giving them out.. Got mine back in 2011 though, so no promises.. But its a fun test, if your up to speed on ipv6 you can run through it a few hours easy.. I did one lazy sunday afternoon.. Biggest thing was getting the IPv6 glue setup on a domain..

This is true - just hope your "clients" have IPv6 -- hehe.. Ask your typical user what their IP is even IPv4 and they look like a deer in headlights.. But yeah that is one actual use for it in a home setup - getting around CGnat in the IPv4 space.

jpvonhemel

@johnpoz I just have to quiz my wife what our subnet private addresses are, or the unifi controller IP, and instant deer in the headlights.

johnpoz

@jpvonhemel haha, I get it with normal "users" but ask some so called tech guys what their public IP is - they didn't have a clue.. One of my buddies has some shit home wifi router thing at home.. And I ask him why you don't setup a decent network at home.. He spends all day doing firewalls and routers and switches, etc.. So he just wants to turn off at home.

I get that sort of - but to me IT while its work, is also my hobby/fun.. Stuff I can't play with at work, I can play with at home, etc. Like IPv6 ;)

There are plenty stuck behind CGNAT in North America too. My ISP, Rogers, provides IPv6 on both cable and cell networks. On the other hand, the big phone company doesn't yet offer IPv6 to consumers on their ADSL or fibre networks and doesn't properly support it on their cell network. My work phone, on that company, it gets only 1/10 on test-ipv6.com. "Danger IPv6 sorta works - however, large packets appear to fail...". They also don't provide IPv6 to devices connected to the hot spot.

@johnpoz

Many "tech guys" don't get a lot of things. For example, look at all those who run Windows as admin. That leaves them wide open to malware. On my own computers, I run as a mere mortal, with admin rights when needed, just as I do on Linux.

Many are also not that great on network issues.

jpvonhemel

@jknott Considering our dependency on Windows, I expect to wake up one day and find out that Windows Update promulgated a delayed signed ransomware attack that simultaneously devastated both the enterprise and retail installs, and this then proceeds to global catastrophe.

@johnpoz

Well this is FRUSTRATING AS HELL!!! Got up this AM - noticed that I had a new IPv4 Address on WAN from COMCAST - but the IPv6 one did not change. So I went to the IPv6 test page and now see what I get:

I have done done this page too - where COMCAST support sent me:

This makes no sense - at all. Verified that IPv6 is still setup on the NIC of the Server - the same STATIC addresses I put there.
