RUT200 - No PING with IP4?

NETWORKING SOLUTIONS

Hi,
I am unable to ping an IP4 address. These are my test targets:

mprowe@localhost:~> nslookup bbc.co.uk
Server:         192.168.8.1
Address:        192.168.8.1#53

Non-authoritative answer:
Name:   bbc.co.uk
Address: 151.101.0.81
Name:   bbc.co.uk
Address: 151.101.64.81
Name:   bbc.co.uk
Address: 151.101.192.81
Name:   bbc.co.uk
Address: 151.101.128.81
Name:   bbc.co.uk
Address: 2a04:4e42:200::81
Name:   bbc.co.uk
Address: 2a04:4e42:600::81
Name:   bbc.co.uk
Address: 2a04:4e42:400::81
Name:   bbc.co.uk
Address: 2a04:4e42::81

If I try an IP6 address, all good:

mprowe@localhost:~> ping 2a04:4e42:200::81
PING 2a04:4e42:200::81(2a04:4e42:200::81) 56 data bytes
64 bytes from 2a04:4e42:200::81: icmp_seq=1 ttl=55 time=36.9 ms
64 bytes from 2a04:4e42:200::81: icmp_seq=2 ttl=55 time=28.5 ms
64 bytes from 2a04:4e42:200::81: icmp_seq=3 ttl=55 time=36.7 ms
64 bytes from 2a04:4e42:200::81: icmp_seq=4 ttl=55 time=42.0 ms

But trying an IP4 address. No go…?

mprowe@localhost:~> ping 151.101.0.81
PING 151.101.0.81 (151.101.0.81) 56(84) bytes of data.
From 192.168.8.1 icmp_seq=1 Destination Net Unreachable
From 192.168.8.1 icmp_seq=2 Destination Net Unreachable
From 192.168.8.1 icmp_seq=3 Destination Net Unreachable
From 192.168.8.1 icmp_seq=4 Destination Net Unreachable

IP4 works on local workstations (LAN?) but not out to the WAN. How do I check that IP4 is enabled for the modem (mob1s1a1)?

Or any other thoughts on where I should look?

Hello,

It seems that your device is receiving only an IPv6 address. You can check this by going to Network → WAN and looking at the active mobile interface IP address. However, you can force your device to get an IPv4 address (if your carrier supports it). To do this, go to Network → WAN, then click “edit” next to the active mobile interface. In the new pop-up window, change the PDP type to IPv4. After restarting the modem or the entire device, you should receive an IPv4 address.
