In ESXi can't access guest OS (Ubuntu 8.10) from outside

[Bailywolf]

Here's the specs on the box:

Supermicro
Xenon 2.8Ghz
1GB RAM
2x 80GB SATA drives

ESXi version - 3i 3.5.0 build-123629

Current Config
4 VM's configured for Ubuntu Linux
1 currently installed with Ubuntu 8.10 Server (intended to be a LAMP web server).

Issue:
I can access ESXi just fine via the management client, start, stop, and config all my VM's. That seems to be working fine.

I can term into the Ubuntu install and work with it, update it, and install applications via CL or the package manager.

I can access the web via Firefox from within the Ubuntu guest.

It's a bog-standard Ubuntu LAMP with a few of my favorite helper apps (Webmin, for example). Nothing weird, and nothing I haven't installed identically for a standalone box.

Problem is, if I assign the guest a static IP, I lose all connectivity to and from it. Without a static IP, it gets one from *somewhere* (from esxi?) and so I can access the outside world, but can't access the Ubuntu guest from outside.

With a static IP (all the network settings triple-checked) I can't ping the box or ping from the box.

There has to be something obvious I'm missing- how do I get the guest OS to behave like a proper webserver?

Thanks,

If I remember correctly ESXi has a virtual switch. If you change from DHCP to Static you may need to look at the VSwitch and its VLAN configuration ... just a thought.
