Can only remote into azure vm from DC
Hi all, I have set up a site to site connection from on prem to azure and I can remote in via the main dc on prem but not any other server or ping from any other server to the azure. Why can I on...

Please try to fix by below:
1. Check Azure NSG rules
- Go to the VM’s NSG and confirm it allows inbound RDP from your full on-prem subnet (e.g., 10.0.0.0/16), not just the DC’s IP.
2. Verify VPN configuration
- Ensure the local network gateway in Azure includes the full on-prem subnet range.
- Confirm the VPN gateway is connected and routing correctly.
3. Add static routes on other servers
- On each server that cannot reach Azure, run:
route add <Azure subnet> mask <subnet mask> <RRAS server IP>
4. Enable IP forwarding on RRAS
- Make sure RRAS is configured to forward packets between networks.
- Check that NAT or firewall rules aren’t blocking traffic.
5. Use internal routing or redistribute routes
- If you have an internal router or Layer 3 switch, redistribute the Azure route from RRAS to your internal network.
