Description

Steps that may possibly reproduce.

1 - enable "IPv6 over IPv4 Tunneling" and set an ip address in the "ipv4 address of tunnel peer field"
2 - save and apply
3 - disable "IPv6 over IPv4 Tunneling" and empty the "ipv4 address of tunnel peer field"

This error pops up.

"Fatal error: Uncaught Error: Cannot unset string offsets in /usr/local/www/system_advanced_network.php:112 Stack trace: #0 {main} thrown in /usr/local/www/system_advanced_network.php on line 112 PHP ERROR: Type: 1, File: /usr/local/www/system_advanced_network.php, Line: 112, Message: Uncaught Error: Cannot unset string offsets in /usr/local/www/system_advanced_network.php:112 Stack trace: #0 {main} thrown"

If page is reloaded, the box is unticked, there seems to be a value of "1" left as the "ipv4 address of tunnel field" config.

The problem is even if its successfully disabled, now changing "any" setting on that networking page will throw up the php error, so unit is damaged.

I am reporting the bug, but also a request is if there is a way to now manually fix the config. So I am not resorting to setting up the unit from scratch to clear the error.

missed step 4 which is hit save and apply again.

Raising urgency of bug, as it seems it does actually prevent toggling other settings on the networking page. Until I fix the config my settings on that page are now locked in place, unless I enable the "ip[v6 over ipv4 tunneling again".

lower urgency now.

I fixed my local config with viconfig.

The setting that got stick is 'ipvnat'

It looked like this in the config

<ipv6nat>1</ipv6nat>

I removed the 1 and its normal again.

So if you follow the steps provided it should get in that stuck state.

That's a new error, not the same one. I can't reproduce that here, but I can see how it might happen. Pushed a new fix.

Tried on 2.4.4-p3. I do not observe the issue.

0. set IPv6 on LAN
1. enable "IPv6 over IPv4 Tunneling" and set an ip address in the "ipv4 address of tunnel peer field"
2. save (there is not apply only save)
3. empty the "ipv4 address of tunnel peer field" and disable "IPv6 over IPv4 Tunneling" (empty and disable not vice versa, because if disable is performed, then field disappears)
4. save

Config looks fine:

Enabled

<ipv6nat>
    <enable></enable>
    <ipaddr>192.168.128.240</ipaddr>
</ipv6nat>

Disabled

<ipv6nat></ipv6nat>
