#NAT in #IPv6 ( https://packetpushers.net/podcasts/ipv6-buzz/ipb194-naval-gazing-at-nat-in-ipv6/ ). 🤔
Don't "bring back #IPv4 habits", but networks hit real constraints. 🤷‍♂️ If your internal v6 addressing is tied to an #ISP prefix, then multi-homing, provider changes, or failover get messy. Renumbering is painful and running #BGP everywhere is unrealistic for branch designs. In those cases, v6-to-v6 translation, #NPTv6 (prefix translation), can be a practical shim to keep a stable internal prefix and translate it to the provider prefix at the edge.

Just over a month and I've tamed all the #trunks (with abundant snake heads at the end), made sure 1500+ #blighters are yeeted (with more trying every day) got inter #PBX #trunk working between on-premises and cloud #FreePBX - just waiting for porting of first analogue number to check this (and CLID presentation) works and then main office one can follow.

Took many late evenings, a lot of research of everything from old #BritishTelecom training manuals to some from Universities in India and the Indian telecom companies, and I've learned a lot more about #SIP even since 2008 when I built the first #VOIP #PBX used at work.

Thankfully #routers seem to handle #SIP over #NAT a lot better than they used to (even got an extension it working over #LTE with #Linphone)

Does anyone believe that Australian Liberal or Nat politicians are in politics for anything but self enrichment?

They will cultivate miners, big business, bankers and cosy up to the demented #USA govt in order to gain power and control, increase their personal assets and set themselves up for a future beyond government.

Look at the present occupations of Cormann, Hockey, Downer, Pyne and the slimy Morrison. Just a few examples, check Wiki.

All now on boards, or partners in consultancy, or advisory capacities, only through their previous liaisons and political networking.

Not saying this doesn't happen to some extent w others, but at least #Labor, #Greens and #Inds attempt to seek improvement during their time in parliament rather than continuously oppose, destroy or subvert for their personal benefit.

Now my little bandwidth-monitor project for OpenWRT and Linux Routers is pretty complete.

It supports Adguard Home, Pi-hole and nextdns.io for the DNS tab. And has a Unifi integration to get the Wifi Status. (Might add Omada later)

Additionally I added a Speedtest capability and some Debugging Features.

Also you can see your #Conntrack #NAT status.

Как я выяснял, что провайдер блокирует входящий 443 порт, и что это означает для self-hosting и хомлабов

В какой-то момент я решил заняться self-hosting’ом дома: небольшой хомлаб, Proxmox, несколько сервисов за reverse proxy, HTTPS - всё максимально стандартно. Никакой экзотики: обычный домашний интернет, белый IP, проброс портов, nginx с TLS. Но на этапе публикации сервисов наружу выяснилось странное: входящий 443 порт просто не открывается , при том что 80 и другие порты работают.

Gặp vấn đề NAT hairpinning: khi truy cập các dịch vụ (memos, owncloud…) qua domain nội bộ trên router BT Smart Hub 2, yêu cầu luôn timeout, trong khi ngoài mạng hoặc VPN thì bình thường. Router không hỗ trợ NAT loopback. Giải pháp khả thi: dùng Cloudflare Tunnel (cẩn thận FUP), hoặc thiết lập VPS + Pangolin, hoặc nâng cấp router hỗ trợ NAT loopback (VD Ubiquiti Dream Router 7). #NAT #hairpinning #homeLab #router #Selfhosted #Mạng #CôngNghệ #Vietnam

Your daily reminder that #NAT is not a security mechanism and the lack thereof is meaning something is unsafe. #ipv6 https://www.johnmaguire.me/blog/ipv6-is-not-insecure-because-it-lacks-nat/

Had to open 5060 inbound to get one providers trunk to signal inbound calls (either #STUN isn't working there or some #NAT issues), with predictable results..

Got older version of #fail2ban on this box to yeet all blighters trying to get in - by turning on security logging in /etc/asterisk/logfiles_custom.conf (add entry security_log => security), updating regexes in /etc/fail2ban/filter.d and pointing failt2ban jail to check /var/log/asterisk/security_log (main Asterisk log is in wrong format and I don't know enough regex to fix that)

Also registered a #Voipfone virtual PBX extension to use as an extra trunk (needs contact-user and from-user set in #PJSIP config)

The picture @alex drew a few months back sums up exactly what dealing with these #VOIP #trunks is like

@BestGirlGrace the only reason I use #SSH tunnels is because they work reliably.

• I really need to see if I can use #dropbear with #pwnat to get some public-reachable SSH server persistently through #NAT|s.

@louis Once Provider-Independent #IPv6 isn't #paywalled with a @ripencc membership, #NAT66+#ULA works as well across #WAN links as #IPv4+#NAT and all vendors of Software and devices support IPv6 with Privacy Extensions enabled per default!

@happyborg @dalai @jwildeboer most of these providers claim that they can recoup the cost with new purchases and shrinking costs for storage over time, which makes this truly a #PyramidScheme.

• OFC they also throtthe users and don't expect everyone to max out their purchased storage quota instantly.

• But I'm not just comparing against short-term filehosters but also in terms of #backups consider years, if not decades of uptime to be necessary to be useful.

Also mind you this ain't like #TeamViewer where the cost of infrastructure is negligible (just some "Rendrevous-Server" to exchange status info, IP addresses and facilitate "Hole Pubching" through #NAT & #Firewall which in theory doesn't reuire mich compute and bandwith to function.

• We're talking Gigabytes if not Terabytes per User in storage and traffic.

• And since this system isn't like some #ColdStorage like a #tape, this needs to be #HDDs that constantly spin and draw power.
