No ipv6 default route after basic configuration

[rdmitry0911]

Expected Behavior

After enabling ipv6 in OMR Adv. Settings, disabling 6in4 and filling ipv6 addr/router for both wan1 and wan2 there should be a default route in ip -6 ro show ta all for all the ipv6 traffic

Current Behavior

ip -6 ro show ta all:

Possible Solution

Steps to Reproduce the Problem

1.Install last OMR from here
2.Make basic ipv6 config for both wan1 and wan2
3.Try to ping6 google.com

Context (Environment)

I have VPS with public ipv6 address and private ipv4 address. So it can be accessed from outside only via ipv6

Specifications

• OpenMPTCProuter version: openmptcprouter v0.62-6.6 r0+28431-92e020b50f
• OpenMPTCProuter VPS version: Not used
• OpenMPTCProuter VPS provider:Not used
• OpenMPTCProuter platform: x86/x86_64
• Country: Greece

There is a bug on the interface on 6in4 disabling, try via SSH: uci set openmptcprouter.settings.disable_6in4="1" && uci commit openmptcprouter and to be sure reboot.

[rdmitry0911]

uci set openmptcprouter.settings.disable_6in4="1" && uci commit openmptcprouter

Didn't help. After reboot:

root@OpenMPTCProuter:~# ip -6 ro sh ta all|grep default
default from fe80::a00:2 dev 6in4-omr6in4 table 61201 proto static metric 1201 pref medium
default via fe80::a00:1 dev 6in4-omr6in4 table 61201 proto static metric 1201 pref medium
root@OpenMPTCProuter:~#

I would need the result of uci show openmptcprouter.settings via SSH on the router please

I'm not able to reproduce the issue, when 6in4 is disabled I don't have issue with local IPv6 connections.
You can try to delete omr6in4 interface in Network->Interfaces
