WSL failing to route network packets e.g. ping

[wtfrank]

Windows Version

Microsoft Windows [Version 10.0.19045.2728]

WSL Version

1.1.3.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.90.1

Distro Version

Ubuntu 22.04

Other Software

No response

Repro Steps

1. Demonstrate windows network connectivity is working by launching cmd.exe
2. ping well know ip addresses such as 1.1.1.1
   C:\Users\user>ping 1.1.1.1

Pinging 1.1.1.1 with 32 bytes of data:
Reply from 1.1.1.1: bytes=32 time=12ms TTL=54
Reply from 1.1.1.1: bytes=32 time=10ms TTL=54

Ping statistics for 1.1.1.1:
Packets: Sent = 2, Received = 2, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 10ms, Maximum = 12ms, Average = 11ms
Control-C
^C

3. Demonstrate WSL2 network connectivity is broken by launching WSL2
4. ping well known ip addresses such as 1.1.1.1 or 8.8.8.8

Expected Behavior

Expected: ping response from remote hosts when pinging from inside WSL2 with ping 1.1.1.1

Actual Behavior

Actual: no response from remote hosts

$ 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 ---
17 packets transmitted, 0 received, 100% packet loss, time 16670ms

$ ping 1.1.1.1
PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.
^C
--- 1.1.1.1 ping statistics ---
4 packets transmitted, 0 received, 100% packet loss, time 3122ms
