looks good for VyOS 1.5-rolling-202404260019 and VyOS 1.4-stable-202404120309

It looks working on VyOS 1.5-rolling-202404260019

set system domain-name 'vyos.local'
set system host-name 'r4'
set system static-host-mapping host-name r4.vyos.local inet '100.64.0.14'

Perhaps those changes should be within the firewall context?

Hi Giggum,
our previous solution was IPv4 only and not so nice integrated in VyOS,
therefore there are several reasons why a rework is a good idea.

Im thinking since sysctl can be changed after the system have completed its boot shouldnt the "system sysctl" be runned among the last tasks according to "/usr/libexec/vyos/priority.py", which would also fix this issue ?

@adestis did your previous solution account for non-IP address characters in a given blocklist? For example the https://www.spamhaus.org/drop/dropv6.txt list has a bunch of stuff that would need to be ignored.

@Apachez, there is no easy way to fix anything related to sysctl, until one component depends on another.
Especially, for example, if we have to deal with "dynamic" interfaces.
Globally, this task is still open and could contain subtasks.
Thanks!

Note that "base_reachable_time_ms" is still valid while "base_reachable_time" is obsolete.

Allowing only ethernet interface task https://vyos.dev/T6265
After adding check, this task can be closed

Will be available in the next rolling release.

       The base_reachable_time and retrans_time are deprecated.  The
       sysctl command does not allow changing values of these
       parameters.  Users who insist to use deprecated kernel interfaces
       should push values to /proc file system by other means.  For
       example:

       echo 256 > /proc/sys/net/ipv6/neigh/eth0/base_reachable_time

I propose to add new option under interface

set interfaces ethernet eth1 ip[v6] base-reachable-time xxx

This sysctl option is deprecated https://man7.org/linux/man-pages/man8/sysctl.8.html

Hi everyone, I think I found the simplest configuration that can reproduce this problem. If we set up firewall and use this command(set system sysctl parameter net.ipv6.neigh.eth3/2) in configuration at the same time, an error message will show when startup.
This is an example

set firewall
set interfaces ethernet eth0 address 'xxx.xxx.184.32/24'
set interfaces ethernet eth0 hw-id 'xx:xx:xx:xx:xx:50'
set interfaces ethernet eth1 hw-id 'xx:xx:xx:xx:xx:ba'
set interfaces ethernet eth1 vif 2
set interfaces loopback lo
set protocols static route xxx.xxx.0.0/0 next-hop xxx.xxx.184.1
set service ntp allow-client xxxxxx 'xxx.xxx.0.0/0'
set service ntp allow-client xxxxxx '::/0'
set service ntp server xxxxx.tld
set service ntp server xxxxx.tld
set service ntp server xxxxx.tld
set service ssh
set system config-management commit-revisions '100'
set system conntrack modules ftp
set system conntrack modules h323
set system conntrack modules nfs
set system conntrack modules pptp
set system conntrack modules sip
set system conntrack modules sqlnet
set system conntrack modules tftp
set system console device ttyS0 speed '115200'
set system host-name xxxxxx
set system login user xxxxxx authentication encrypted-password xxxxxx
set system sysctl parameter net.ipv6.neigh.eth1/2.base_reachable_time_ms value '14400000'
set system syslog global facility all level 'info'
set system syslog global facility local7 level 'debug'

If delete the first line (set firewall), system will start normally without error message.

So most likely we will have to find another implementation.

I sent a question to ISC regarding https://www.isc.org/blogs/dhcp-client-relay-eom/ and:

Reopen to investigate.

I tested in the latest rolling version and the traceback error is not received anymore and the tunnel ip column shows n/a but with multiple entries.
It still shows the disconnected client and I assume it should not show disconnected clients

Close it as wontfix due to legacy backend.

In some cases, we can't predict the interface name (if the interface name is over 15 characters) https://vyos.dev/T6222

@sempervictus Any updates or additional context?

Fixed, VyOS 1.5-rolling-202404240023

Interface "tun0" cannot be deleted as it is a member of bridge "br0"!

@doctorpangloss Any updates?

@modzilla99 Could you provide an example of set commands to reproduce?
