No intranet network connectivity from RHEL5 VM (running on Dell PE1950)

I've installed ESX4 on an old Dell 1950 to start consolidating some RHEL5 servers.

The host has two Broadcom 5708 NICS, however only one is currently connected to a network. The current networking configuration consists of a single vswitch, with a VM Port Group and a Service Console attached, connected to the sole active NIC.

I created a guest os with default options, specifying the guest to be RHEL5 32 bit. I initially attempted to PXE boot the VM however did not recieve a DHCP offer and /var/log/messages on the DHCP server did not show a request coming from the new MAC.

As a fallback, installed the VM using an iso, using a static IPs. After install, tried to ping some of the hosts on the intranet (on the same subnet). I am able to ping localhost, the local static ip and the IP of the service console, but everything else is being reported unreachable.

Logging into the ESX console, I am able to ping both the VM and all ips on the intranet. Is there some configuration I need to do to allow the guest VM access outside of the ESX sandbox?

While I couldn't get a straight text dump of the esxcfg output I copied down the details:

esxcfg-vswif -l:

vswif0 Service Console IPv4 192.168.81.102 255.255.0.0 255.255.255.255 true DHCP

esxcfg-vswitch -l:

vswitch0 32 4 32 1500 vmnic0

VM Network 0 1 vmnic

Service Console 0 1 vmnic0

esxcfg-nics -l:

vmnic0 03:00:00 bnx2 Up 1000Mbs Full 00:50:56:1d:fe 1500 Broadcom BMC5708

vmnic1 05:00:00 bnx2 Down 1000Mbps Full ...... 1500 BroadcomBMC5708

Solved it.

Turns out my switch (Catalyst 3750) was blocking the additional MACs. Reconfigured the port security settings and everything now seems to be fine.
