Questions & Answers / Maximum /48 alocation
Last post by leandroneves - May 04, 2026, 09:43:47 AMDear HE.NET team,
I needed to reorganize my network and establish connections to tunnels with lower latency. For Missouri, I connected to Chicago and everything went well. In São Paulo/Brazil, I did the same procedure. The tunnel with the lowest latency is New York.
However, when I tried to create the new /48 block between São Paulo and New York, the platform sent me the message: "Error: Maximum /48s requested. Please try again later."
Does this refer to my maximum number of tunnels (I only have one) or the maximum available from HE.NET in New York?
If it's the former, I would kindly request that you correct my profile so that I can allocate the tunnel.
By the way: I understand that you work with high volume, but as a user, allocating more /56 tunnels might be more valuable than a few /48 tunnels.
I want to thank you for the years of service together. Thank you!
Best Regards,
Leandro Neves

IPv6 on Windows / Re: unreachable from outside
Last post by cnsh - April 30, 2026, 04:09:42 AMI checked everything. From firewall inbound/outbound rules and general firewall settings to registry keys (Ifiso settings and etc). EVERYTHING. Firewall logging won't work (even after restart), and I have no clue how to fix this damn issue.
Thinking that it might be Windows side issue. Will submit a bug report today, even though noone will look into it, I'm enough fed up with this thing.

General Questions & Suggestions / Re: Zone limits was changed?
Last post by patthoyts - April 22, 2026, 04:06:18 AMI had the same issue, a re-login did not resolve the problem but clearing the dns.he.net cookies and then logging in again did sort it out.

Another issue from deleting that comes at some windows features ending up bricked completely. Advanced windows firewall, media streaming settings, and various other stuffs won't start and gets bricked. Is there a way that it won't brick any of the windows services while getting that IfIso removed?
Code Select
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\RestrictedInterfaces\, and it works on private profile too. Problem solved?

Last post by Agouros - April 19, 2026, 06:17:40 AMHi,
I just finished Sage Level in the certification. What Do I need to do to be able to unblock SMTP? I currently do not see an a 'unblock' button under tunnel details -> advanced.

Changed my NIC's network profile from private to public, now everything works as it should be.
Someone explain why this happens although I have allowed IPv6 traffic on all private, public, and domain profiles.

IPv6 on Windows / Re: unreachable from outside
Last post by cnsh - April 18, 2026, 06:40:53 AMslight update.
I tried making a rule both on inbound&outbound to accept any kind of traffic at any kind of protocol, but it still doesn't open v6 port.
Instead, the connection works flawless when I disable the firewall completely from the control panel.
I'm still researching for further solutions. Trying to log the firewall, but the logfile stays at 0KB and completely blank whatever I do. I might try checking that log tomorrow to see if it does record anything at all.
EDIT: I solved the issue by changing the nic's network profile
