Thanks Treepose,
The netstat command revealed that the 172.16.X.X
management network was in the routing table, but only specified as a broadcast address 172.16.232.255 or a subnet; 172.16.232 /24
I'm obviously a networking newbie and don't know the correct interpretations for a lot of this information. Plus the VMware adds another layer of abstraction to straighten out. For example, the 172.16.232.128 (my management IP) should only exist with the virtual emulation, but my router has to know it's there in order for my browser to communicate with it. Is there a way to do that? For now, all I can do is access the GUI through the internal self IP (which I know is not recommended) .
What's setting me back even worse is that "b reset" - to wipe out all my settings and start from scratch - is registering as an invalid command. But again, maybe this is an artifact of working with a simulation and not the real thing. Nonetheless - it's nice to have an BIG IP to poke around on !
I'm suspecting the problem might have something to do with the way I set up my host (Using a real qualified domain from dynDNS the first time. Now I'm using a dummy domain, but maybe it doesn't matter). My original BIG IP VE setup had a management IP that was actually accessible..... BUT - none of the pool members were reachable !
Living and learning. - treepose_102627Historic F5 Accountb reset isn't a supported command for BIG-IP. There are manuals around to peruse... here's the method: "b import default" - and this KB entry applies (taken from the release notes: )
"bigpipe import command (CR136004)
Use of the b import default command can generate Security-Enhanced Linux (SELinux) errors. You can ignore these errors."
If your workstation (Web Browser) is on the same subnet as your LTM VE's mgmt port, your router shouldn't come into play. Host only and NAT'd networks accomplish this. Short of that, reviewing how layer2 and layer3 networking plays with each other is probably a good idea. - net_enthused_25

Thanks, Treepose
I'll try and read up on the literature (there's no shortage of it) and figure out what's going on.
I initially thought it a good idea for the management IP to be on a separate subnet from my actual subnet, as I understood that this was closer to a real world usage scenario.
Thanks again,
dwc - treepose_102627Historic F5 AccountNet_enthused: One style of deployment involves three subnets. One for mgmt, one for "internal" traffic and one for "external" traffic. This is covered in the release notes with configuration examples.

I think I understand that deployment configuration fairly well, as that's what I'm trying to establish.
The problem is that if my management port is located on a 172.16.232.x , and my actual computer subnet is 192.168.1.x , my browser has no idea how to reach the mgmt IP.
I'm guessing that my router searches for 172.16.232 and ends up hopping out into the internet instead of back into my box. I tried to establish a static route in my router, but that didn't work. This issue might be related to the layer of abstraction that the VMware adds, but I'm not sure. - net_enthused_25

addendum -
I'm pretty sure at this point it's an issue with my VMware
network settings. And nothing to do with my router. I have the VMware Fusion network settings set for "Host Only" and they seem to be pointing at the right 172.16 network... but how that bridges to my own actual 192.168 network is still hazy to me. If it's all a layer 2 issue, they're all on the same box and should be honking at one another just fine. Hmm.... - qe_102628

net_enthused: Your Fusion host should have a virtual interface in the 172.16.232 network. It's will be one of the vmnet interfaces that shows up when "ifconfig -a" is ran inside of a terminal window. I hope that will clear up your haze. - net_enthused_25
Nimbostratus
Yep - the vmnet networks were the key. I had actually
designated an management IP with the exact IP address of the Fusion virtual machine; which created a conflict. When I stayed with that network but changed to a unique host address, my problems were basically solved. I'm sure it was staring at me in the documentation somewhere.
Good call qe; thank you ! - hoolio

Did this post get moved at some point? It looks like it's in the Advanced Design/Config section, not the VE forum.
