Azure Site to Site on Premises

Question

Hello,

I have successfully created the Site to Site VPN tunnel from on premises to Azure and the tunnel is up on both the ends. I cannot ping from on premises to Azure network, I have checked from the on premises firewall and found the packets are reaching azure but cannot get reply. Any help will be appreciated.

I went to network watcher then connection troubleshoot it showed me the below image

my on premises lan is 192.168.1.0/24 and Azure is 172.168.1.0/24

Thanks

Hello @skak ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

Looking at the shared image, it looks like the the Azure VM with IP address 172.168.1.9 has connectivity issues. I would advise you to check the below:
NSGs applied on the VM & it's subnet which could be blocking the connectivity.
Any UDRs on the VM's subnet.
VM's OS Firewall blocking traffic. Try allowing ICMP or disabling the Firewall.

Kindly let us know if the above helps or you need further assistance on this issue.
