Which wizard suggested that switch?

IMHO: its a BAD IDEA(tm)

1)Bridged requires that your nic be aliased (run in promiscuous mode)
and it requires that it obtain an additional IP via dhcp. While
this is usually possible on a real nic, its quite likely that dial-up
or ADSL will nor support more than one IP per nic. Neither
will many (if not most) wireless nics. This is usually a show stopper.

2)Bridged exposes your VM to the net which in turn means you
have to start worrying about running a firewall in the VM and
all the other issues you encounter when putting a machine on
the net.

This is the beauty of VmWare nat. First, it just works. Second it
provides a layer of protection to the VMs, allowing you to run
vulnerable OSs there (read Windows) without the need to run
resource hogging virus scanners.

So, short answer: Even if point 1 didn't kill you, point 2
makes it a bad idea.

This is most likely NOT a firewall issue. Bridged runs beside your
firewall, not behind it.
