Hello! I have been trying to figure this out for a few days to no avail, perhaps one of you could shed some light on the situation:
For reference, I would consider myself competent with computing and networking in general, but not really with VMWare. We have an old Dell PowerEdge R510 that we are re-deploying for VMWare. The end goal is to have three DCs and Alienvault successfully up and running.
I installed the 5.5 Update 3 image (the latest supported for the R510, and it works since we already have a 5.5 license from long ago) from Dell smoothly, set up the management network, gave it a hostname, made an entry in DNS, navigated to the hostname: Great, things are smooth. I fired up vSphere and did the same. I set up networking next. We have three VLANs (10, 20, and 30), one for each of our businesses. So, I added those three VLANs in the form of port groups to the default vSwitch. I also added the second NIC that is on our server to the vSwitch and plugged it in, as I found in this best practice guide (page 16). I then attempted to deploy Alienvault first. I attached each NIC on Alienvault to the second VLAN, 20, as this the main business. Fired up the VM, and network conenctivity failed: Great, things are not smooth. I am much more versed in Windows than any other OS, so I created a test Server 2k12 VM. After lots of troubleshooting these are my findings:
When on VLAN 0 or 4095 the test VM can ping ESXi (also on 0 or 4095), but nothing else.
When on any other VLAN, the test VM cannot ping ESXi (neither on 0 or 4095), nor anything else.
In my week of testing, never once have I been able to successfully ping any other machine: Gateway, DNS, another machine on the same subnet: nothing.
All of the testing above was done with valid static IPs in the network and not DHCP. I should note though, that DHCP pulled a 169.xxx address 100% of the time it was in use.
Originally I saw on Google that people have been successful in trying to install 6.7 on this generation of servers (apparently the R710 is a staple in the homelab?), so that was my first course of action. I successfully installed 6.7 and did everything I did above (with the free version, not licensed like our 5.5 is), but to no avail. I thought it was likely a hardware incompatibility issue somewhere since 6.7 is not supported on our server, so that is when I went the 5.5 route, also to no avail.
What am I missing? I have tried practically everything I can think of, including isolating the test machine to it's own vSwitch with the second NIC attached to it.
Below I have attached a screenshot of my networking tab in vSphere, more can be provided if necessary.
