A Mikrotik cloud hosted router has been installed on a VM in Azure using the following OS link:
https://download.mikrotik.com/routeros/6.49.18/chr-6.49.18.img.zip
Service Plan:
CPU: 1 core
RAM: 1 GB
OS: Ubuntu 22.04
The installation was performed with these commands:
wget https://download.mikrotik.com/routeros/6.49.18/chr-6.49.18.img.zip -O chr.img.zip
gunzip -c chr.img.zip > chr.img
dd if=chr.img bs=1024 of=/dev/sda
Despite setting the required inbound rule for TCP port 8291, connectivity via SSH (port 22) and Inbox (port 8291) is not successful. Any suggestions for troubleshooting this connection issue?

Here are few troubleshooting steps you can check for the connectivity issue:- Validate Inbound Security Rules: Double-check your Azure Network Security Group (NSG) settings. Ensure that there's an inbound rule allowing traffic for both TCP port 22 (SSH) and TCP port 8291 (Mikrotik Winbox).
- Check VM's Public IP Address: Make sure you're using the correct public IP address of the Azure VM to connect. You can find this in the Azure portal under the VM's overview page.
- Verify VM Configuration:
- Ensure that the VM is running and that there are no issues with the VM's status.
- Check if the network interface is configured correctly and matches the expected settings for the Mikrotik router.
- Test Connectivity:
- From another VM in the same network (if available), try pinging the Mikrotik VM to verify that the network is operating as expected.
- Use tools like
tcpingto check if the ports are listening:tcping <your-vm-ip> 22
tcping <your-vm-ip> 8291 ```
- Firewall Settings: Check if there are any firewall rules in the Mikrotik router itself that may be blocking incoming connections on those ports.
