This concerns use of Turris Omnia router with Australia’s largest telco’s (Telstra’s) 5G home internet modem.
I have a Turris Omnia freshly reconfigured from latest medkit. Versions are later in this post.
The upstream modem reports via DHCP its own local DNS server addresses 192.168.0.1 and 2001:8004:1de1:b36b::1 which when using Windows directly with the upstream modem works just fine, and both ipv4 and ipv6 address are pingable from Windows.
But when Turris Omnia is connected, the following is seen where the ipv6 address is not pingable on the directly-connected device even though ipv6-only dns ipv6.google.com is pingable.
It looks like there’s some kind of routing problem happening with ipv6 traffic on Turris, that does not happen on Windows networked the same way.
I’m not terribly familiar with ipv6 routing but could the nexthop in the below be part of the problem, quoting from the detail under the “Turris interface status” heading further below:
{
"target": "2001:8004:1de1:b36b::",
"mask": 64,
"nexthop": "::",
"metric": 256,
"source": "::/0"
},
Foris reports that both ipv4 and ipv6 are operational.
I don’t know how to fix this, does anybody know how?
root@turris:~# cat /tmp/resolv.conf
search lan

From turris, pinging ipv4 works but ipv6 fails
root@turris:~# ping -c 1 192.168.0.1
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.
64 bytes from 192.168.0.1: icmp_seq=1 ttl=64 time=0.886 ms

rtt min/avg/max/mdev = 0.886/0.886/0.886/0.000 ms
root@turris:~# ping -c 1 2001:8004:1de1:b36b::1
PING 2001:8004:1de1:b36b::1(2001:8004:1de1:b36b::1) 56 data bytes

Pinging google’s ipv6 address clearly works:
root@turris:~# ping -c 1 ipv6.google.com
PING ipv6.google.com(syd09s31-in-x0e.1e100.net (2404:6800:4006:809::200e)) 56 data bytes

--- ipv6.google.com ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 28.514/28.514/28.514/0.000 ms
As a result, nslookup from turris only works on ipv4
root@turris:~# nslookup www.google.com 192.168.0.1
Server: 192.168.0.1
Address: 192.168.0.1#53
