Disclaimer: I know its a first world problem but WTH do you expect from me.

As of yesterday I have 3 wired internet connections, they all suck in different ways.

Cable Connection: 1.25Gb down, feels like 0 up. Randomly disconnects multiple times throughout the day for a few seconds at a time.
Fiber 1: 1Gb symmetrical, crap IPV6, some backend routes are congested as hell and any lightning fries the OTN.
Fiber 2: 2Gb symmetrical, no IPV6 at all, so many levels of Nat I can't even count them.

After a number of emails and (ugh) phone calls I managed to get a real public (probably dynamic, but whatever) IPv4 address and a bridge mode device. No native IPv6 but HE tunnel seems to be working reasonably OK.

I spent a couple hours yesterday fighting with a code signing issue. Didn't know what was going on since I didn't change anything lately. Thought maybe it was some Xcode 26.5 issue or Mac 26.5. Eventually tried on a different machine and it worked.

After tons of digging into it turned out to be an MTU issue when requesting Apple code sign and it chooses IPv6 instead of IPv4. Still don't really know which bit is wrong, but ended up changing enough settings that it worked.

Finally got native IPv6 (a /56) working somehow (either luck or they enabled It since Monday). No MTU issues, no sites thinking HE Tunnel IPs are bots. Pretty pretty pretty pretty good.

@paul Oooh, congrats!

@paul Daayyumm.

Is that ping rate okay though? My half gigabit fiber almost always is just 1-2ms.

@leebennett latency is kind of crap, no idea why but its a thing with them.

@paul was the HE tunnel worth it despite the issues?

@paul amusing to me that code signing is still hard in 2026, but also this is a wild thing. how did you track it down?

@Amdev not with an LLM I'll tell you that, it was going all over the place trying crazy crap and waving its ā€œhandsā€. It did eventually help coming with a simple reproducible case that didn't require a multi minute build.

Basically one of those things where I went back through all the things I changed recently and was like no way it could be that but doesn't hurt to try it.

@paul damnā€¦ tracking this down must have been a nightmare.

@pfandrade not what I wanted to be doing on a Sunday.

@paul This might be solved with TCP MSS clamping if you donā€˜t have native but tunneled IPv6 and run into MTU issues.

@paul I know that feel...

@paul fiber 1 sounds so much like qwest/centurylink (except for me itā€™s zero ipv6, crap would be an upgrade)

But the 1gb was true symmetric and reliable.

But Iā€™m moving soon after 10+ years with this service and now Iā€™m worried about what Iā€™ll get and what Iā€™ll have to pay.

@paul ouch. Here in the UK I managed to find an ISP that just activates the ONT in the house, allowing me to use whatever firewall and router I want (UniFi in my case) as well as a static IPv4 and a static /56 IPv6 PD. Dual-stacked on all 5 VLANs now; will go IPv6-only on my trusted LAN whenever UniFi step up their IPv6 game and provide a built-in NAT64 gateway. It's 900Mb down and 100Mb up, and feels very consistent.
