Connectivity has been restored in my case.

I received the following reply from the ticket I submitted earlier

"It wasn't taking updates earlier, but should be fine now."

Also seeing issues with tserv4.nyc4 as well. was working fine this morning but as soon as I rebooted my router which gave a new ipv4 address I lost all ipv6 connectivity. Oddly enough I have another site still connected to that pop which has not lost connectivity.

so far I checked that ddns updated my ipv4 endpoint ok or at least the tunnel config page says it's been updated.
first wireshark capture shows 209.51.161.14 is replying with icmp type 3 code 3 port unreachable.

have you already submitted a ticket?

March cumulative update.

FWIW not all of microsoft ipv6 issues were fixed.

When creating your tunnel you are presented with the various tunnel servers and their IP addresses.

Questions & Answers / Re: HE tunnel not working with new ISP
« on: August 28, 2016, 11:23:40 PM »
has there been a change to MTU after changing ISPs?

ex. MTU of 1480 for a 6in4 tunnel using a cable provider vs MTU of 1472 for fiber if using pppoe without baby jumbo frames?

@derby

that's pretty much the approach I'm using. I setup an IPv4 only guest wifi SSID on my AP. Netflix is working fine on my ATV

Ya just started acting up for me as well. @Napsterbater if you get a response from netflix can you follow up here?

IPv6 Basics & Questions & General Chatter / Re: IPv6 on DD-WRT

Router ip for 6in4 is not used / needed. router will get ::0 on lan interface / bridge ex. br0.

Also you need to enable either radvd or use dnsmasq for your RAs. Note windows machines will not pickup ipv6 dns from RA. I prefer dnsmasq myself as it will also send ipv6 dns via dhcpv6 other info. There is no need for any scripts.

note radvd was broken for a number of versions.

ddwrt FW is currently in the v28000 range

in any event see http://www.dd-wrt.com/phpBB2/viewtopic.php?p=909299#909299 for config

With Comcast setup dhcpv6-PD with a prefered lifetime of infinity and the delegated prefix should be fairly stable.

IPv6 Basics & Questions & General Chatter / Re: Incoming traffic

You may want to check the firewall settings on your local computer. As an example by default windows firewall will block incoming echo requests over IPv6. I have no issues accessing my computer via RDP but it required allowing all (source) traffic on that port.

General Discussion / Re: HE Certification

It looks like the OP is basically using the default dd-wrt iptables & ip6tables rulesets. Since he did not run -vnL the IFs are not shown. That being said the first of the duplicate IPv4 input chain "accept state new" would be for lo the second for br0. As for IPv6 it may be prudent to add lo but honestly it does absolutely nothing. I have 0 packets from lo over IPv6.

For IPv4 tcpmss clamping would be found in the mangle table by default with ddwrt. For IPv6 the module ip6table_mangle is not loaded by default and if I remember correctly was not included in the ddwrt builds until recently (ish). If he were to move tcpmss to mangle he would have to insmod ip6tables_mangle.ko himself. As for it being in the filter forward table I believe it would be kind of difficult to outright state that it is not acceptable when the netfilter documentation itself shows it in the filter forward table. FYI it works just fine where it is by default.

The IP address in your initial post is for Comcast which supports dhcpv6-pd and the default path broadcast by radvd or dnsmasq should be the fe80 local link for br0. What version of dd-wrt are you running as current versions of dd-wrt for current routers support IPv6 (dhcpv6-pd, 6in4, static native) out of the box.

Note a few recent builds had a compile error which prevented radvd from starting but this has been corrected in the latest build.

FYI the post you referenced is a poor example as it's not really relevent in your situation

Also you may be better served asking how to setup dd-wrt with Comcast in the dd-wrt forums

Questions & Answers / Re: Speed comparison IPv4 <-> IPv6
« on: March 23, 2015, 03:52:16 PM »
I find ipv6-test.com speed tests fluctuate wildly even using the same server. I can definitely confirm speeds > 100 mbps. I regularly transfer data at 100+ mbps. My line rate is 175/175 and I always have speed tests ~ 174/178 with the exception of when my ISP profile was off and I was able to pull in 239/176.
