How to enable/configure devices for SNMP on the workstation?

2VM Clients are using the network adapter LAN and Client1 has an IP add 192.138.1.4, Client2 192.138.1.5, same Subnet 255.255.255.0,and Gateway 192.138.1.10. 1VM Server. Network adapter is LAN and Bridge, IP 192.138.1.3 and same Subnet and Gateway as the clients. They can ping to each other but they can not ping to the Gateway. It says Destination Host unreachable. I'm trying to download on the Clients VM SNMP Tools but it fails. So my question is what am I missing or doing wrong that it not letting me download and to me I think is I need to fix the Ping to the Gateway. I might be wrong. Hopefully its understandable. OH also all three VM's have Defender Firewall Disabled
