There Windows 10 WSL 2 network doesn't work

Question

In my wsl2 ubuntu 22.04 in Windows 10

:~$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:15:5d:f7:3c:a0 brd ff:ff:ff:ff:ff:ff
    inet 172.27.139.188/20 brd 172.27.143.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::215:5dff:fef7:3ca0/64 scope link
       valid_lft forever preferred_lft forever


:~$ cat /etc/resolv.conf
# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/wsl.conf:
# [network]
# generateResolvConf = false
nameserver 172.27.128.1

:~$ ping 172.27.128.1
PING 172.27.128.1 (172.27.128.1) 56(84) bytes of data.

I added nameserver 8.8.8.8 into /etc/resolve.conf and it works for public network. However, I still can't access the commany internal server via VPN or in office.

I also tried changed the vEthnet(wsl) setting or add inbound firewall rules still doesn't work.
