While you haven’t given all of the requisite information to formulate a complete answer, I think I see enough to be able to respond.
The short answer: Don’t bridge in the guest OS, unless you have two virtual NICs that go to two different vswitches in ESX.
If you’ve done what I think you’ve done, and brought all of the physical interfaces of the ESX host under one vswitch and have defined only one vswitch, then you’re done. All you need (and should) do is assign one vNIC to the VM and give it an IP in that VLAN (or set it to dhcp, if you do server addressing that way).
If this is not the setup you have, please elaborate. Otherwise, use the VM’s console to undo the bridge and just use the one network interface in the guest.
