Issue/Introduction
2 gateways that were running on VM Ware Fusion Pro.
- After upgrade of my Mac to BigSur, Fusion was no longer working and I switched to Player (free).
- I restarted the gateway. For one gateway, I can remotely access it over ssh. But for the other, I have the following error message:
ssh: connect to host gw10 port 22: Connection refused
Yet, the sshd service is running, I have the ssgconfig user listed in /etc/ssh/ssh_allowed_users and the iptables seems to be properly configured (see file attached).
Anywhere else I should look at?
Environment
All Supported versions of API Gateway.
Cause
On nonworking gateway "ip a" shows ens33 network interface is being mapped instead eth0 as expected to. This caused the connection attempt to port 22 to be denied.
Resolution
1. Turn the Gateway off
2. Change the MAC address of the network connection used by the VM to the one of ssg_eth0
To edit a VM MAC address, edit the VM network adapter settings
1. Shut down the VM.
2. Navigate to the VM Settings > Network Adapters page for the VM you want to edit
3. For the network adapter you want to edit, click Edit
4. Edit the MAC address using the guidelines listed below:
- Must be unique on the network.
- Must begin with the hexadecimal digits 00:50:56.
- The valid MAC address range is 00:50:56:00:00:00 to 00:50:56:3F:FF:FF.
5. Click Save Network Adapter.
3. restart the gateway

Another file to look at is the /etc/iftab, you want to make sure this mac address is mapped to ssg_eth0 similar to the following:
ssg_eth0 mac 00:50:56:xx:yy:zz
here xx:yy:zz is the mac of your MAC address of your network interface.
