Everything is setup correctly in ESXi, I would suggest there is something in your Workstation 8 config that isn't quite right - does the Network Card on your ESXi VM in workstation 8 definately have the 'Bridged' setting applied (and not NAT), also have you tried checking the 'Replicate Physical Network Connection State' setting?

Finally does your workstation 8 application have full inbound and outbound access through your Physical host machines firewall?
