bookwormstory.social is now reachable as it is hosted by my friend. He said that my ipv4 is broken and my ipv6 works.

Post the output from these commands, don't forget to use code tags where needed.

Please don't bump but edit your previous post to mend it if nobody has yet replied.
Then please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

and the full output of "ip a; ip r"

II don't have a clue how syncthing works (or doesn't in this case) but it looks like it includes appending an ipv6 address and using that to sync over(?).

You might try disabling ipv6 and rebooting.

PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.

PING one.one.one.one (2606:4700:4700::1111) 56 data bytes
64 bytes from one.one.one.one (2606:4700:4700::1111): icmp_seq=1 ttl=55 time=14.6 ms

The problem seems to be w/ IPv4 and it only seems to be the WAN (since 192.168.0.53 reponds)

Since the network setup otherwise looks ok and there're no driver issues:
Do you need https://en.wikipedia.org/wiki/6to4 or https://en.wikipedia.org/wiki/4in6 ?

Edit: though that's not compatible w/ the subject

Update broke my network stack and IDK what to do.

Can you reach IPv4 IPs from the install iso?

ludrol · 2025-03-28 15:56:02

Booted into an already installed Ubuntu and ipv4 worked
Booted into an Arch installation USB and ipv4 didn't work.

seth · 2025-03-28 15:58:44

This is limited to WAN IPv4?
LAN IPv4 and IPv6 worked on the install iso?

Is there some firewall/pihole/whatever in your LAN?

ludrol · 2025-03-28 18:45:07

Yes, only WAN Ipv4 are broken on Install Iso and on installed system

Debian on another machine and Ubuntu on broken machine work correctly so I don't think someone else set up a firewall on the network. (I don't own the network)

Edit: USB tethering from a phone can connect to WAN ipv4 addresses on arch

Edit: relevant pacman.log fragment
iproute2 looks sus

ip r get 1.1.1.1

and feel free to downgrade iproute2, but given the presented information that seems very unlikely.

The LAN IPv4 works, so this will be some NAT issue related to the router.
How did you establish the connection from the intall iso?

Try to establish the carrier manually (or in doubt use wifi-menu from the netctl package) and then obtain the lease using dhcpcd (wifi-menu will do that) and w/ dhcpcd try to alter between DUID and ClientID in /etc/dhcpcd.conf

Concerned behavior would be NMs mac randomization or the router responding badly to the used identification, but NM isn't in the update list.

ludrol · 2025-03-29 23:33:47

I was using iwctl to set up the network and switched to Network Manager.

dhcpcd or netctl wasn't installed and /etc/dhcpcd.conf didn't exist.

My hypothesis right now is that DHCP lease expired and it didn't get a new one or something similar as USB ISO also can't get the ipv4 WAN network and its packages are month old that ware installed on this computer.

sudo dhcping -v

You have a lease and it works for LAN communication, the WAN filtering/NAT breakage has to happen based on some other criteria.

tracepath 1.1.1.1 # you'll not reach 1.1.1.1 but some cloudflare network, eg. 162.158.0.0/15

I don't own the network

Test whether the identification system makes a difference and post a journal from ubuntu for comparism - but you'll likely have to talk to whoever does.
I don't think this is a local "bug", fwwi: https://bbs.archlinux.org/viewtopic.php … 8#p2230278

How I solved this:

0. Installed dhcpcd
1. Switched Network Manager to use dhcpcd https://wiki.archlinux.org/title/Networ … HCP_client
2. Set ClientID and commented out DUID in /etc/dhcpcd.conf
3. rebooted

seth · 2025-03-30 06:07:05

Did you run a cross-test to make sure it's not just a fluke (ie. switch back to DUID and see whether that breaks it)?
Did you set a specific ID or rely on the default pattern?

Fwwi, NM supports this directly if you care: https://man.archlinux.org/man/extra/net … ON_SECTION
