Ubuntu installed in WSL can NOT reach the Internet

Question

Asked before by other people. I used the answers to their questions to get a head start, but still no joy.

My software mix:

Windows 10 Enterprise
WSL version: 2.0.14.0
Kernel version: 5.15.133.1-1
WSLg version: 1.0.59
MSRDC version: 1.2.4677
Direct3D version: 1.611.1-81528511
DXCore version: 10.0.25131.1002-220531-1700.rs-onecore-base2-hyp
Windows version: 10.0.19045.3803
Description:    Ubuntu 22.04.3 LTS

The relevant files:

$ cat /etc/resolv.conf
#Cisco VPN IP
nameserver 10.8.8.8
$
$ cat /etc/wsl.conf
[network]
generateResolvConf = false
[automount]
options = "metadata"
$

After doing all of that I exited out of Ubuntu and WSL. I then ran wsl --shutdown and started over with a fresh PowerShell

ping google.com still fails.

~$ ping google.com
ping: google.com: Temporary failure in name resolution

ping 8.8.8.8 just hangs

$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
^C
--- 8.8.8.8 ping statistics ---
153 packets transmitted, 0 received, 100% packet loss, time 158057ms
$

I also rang a ping on 10.8.8.8 and 10.8.8.4, the name servers for my Cisco VPN. Both just hung:

~$ ping 10.8.8.8
PING 10.8.8.8 (10.8.8.8) 56(84) bytes of data.
^C
--- 10.8.8.8 ping statistics ---
17 packets transmitted, 0 received, 100% packet loss, time 16631ms
$

I also tried pinging my gateway, no joy:

~$ ping 172.19.48.1
PING 172.19.48.1 (172.19.48.1) 56(84) bytes of data.
^C
--- 172.19.48.1 ping statistics ---
17 packets transmitted, 0 received, 100% packet loss, time 16619ms
~$

Here is my "ip route" output:

$ ip route
default via 172.19.48.1 dev eth0 proto kernel
172.19.48.0/20 dev eth0 proto kernel scope link src 172.19.59.151
$

Is there anything else I can to get Ubuntu to reach the Internet while I have the Cisco VPN running?

What is the ping error ? Is google.com correctly resolved by the DNS ? — hidigoudi, Jan 03 '24 at 16:02
Please add more information in your post with the routes table, the ping error output and the IP of your machine. Thanks — hidigoudi, Jan 03 '24 at 16:10
I see you're using Cisco VPN. Can you give more details about your usage of it. — harrymc, Jan 03 '24 at 16:55
@hidigoudi by routes table do you mean the output of ipconfig /all ? I updated my post with the ping error. — user787832, Jan 03 '24 at 16:58
@harrymc all I do with Cisco VPN is connect at the start of the day to reach company resources. — user787832, Jan 03 '24 at 16:59
@harrymc ping 10.8.8.8 just hung. I updated my post with the output. — user787832, Jan 03 '24 at 17:06
@hidigoudi I ran ip route, the output is now on the bottom of my post. Thank you. — user787832, Jan 03 '24 at 17:10
Are you able to ping 172.19.48.1, this is your gateway. If no, this may explain your problem. — hidigoudi, Jan 03 '24 at 17:16
@hidigoudi I updated my post with the output for pinging my gateway. That just hanged too. — user787832, Jan 03 '24 at 17:21
