Recently, I was honing my skills on SNMP, and choose HP Openview to play around. Now where do you install these software’s, obviously in virtual environment. And that is exactly what I did.

Now, my router and other stuff were not local to the subnet, where in bridged vmmet would have resolved the issue – accessing/managing devices. And as you know, for SNMP to work, external devices should be able to reach the SNMP server.



This is what I did to resolve this issue.



There is an special feature in VMware, not everybody knows about it, and I thought this place a good juncture to share this. VMware Natted VMnet provides Port forwarding feature – not advertised though.



Steps:

Edit -> Virtual Network Settings -> NAT “Last TAB” -> Edit -> Port Forwarding -> Add ->

Host port – Incoming Port “dest_port” in the traffic.

Virtual Machine IP address -> “dest_ip” “the vm’s IP.

Port -> change the port if you intend to change it, here is would remain same as “host port”.

Description – Self explanatory.



You would like to forward at least these ports to begin with, further on you can explore and add….
