# How can I connect to Postgres running on the Windows host from inside WSL2?

### Solution:

Here is how I solved this in case somebody has the same problem:

I needed to add a Windows Firewall rule:

• Open "Windows Defender Firewall with Advanced Security" (you can find it by searching in the Start Menu)
• Click "New rule..."
• Create a new TCP/IP rule
• Protocol: TCP
• Ports: 5432
• Allow Connection
• After adding it, click on the newly created rule and choose "Properties..." from the sidebar
• On the Scope tab, specify the IP address of your WSL2 virtual machine (E.g. 172.31.208.0/24)

If you do everything else in my original question (get both IPs, add VM IP to pg_hba.conf), then connecting to the host IP from the WSL2 command line will work.
