I'm using VMWare Server 2 on WIndows 7 x64 and set up VM with NAT connection to the host. However I just found I can connect to outside with UDP from the VM but TCP connections always fail.
Configuration is as follows:
Guest OS NIC:
IP 192.168.169.128
Default GW 192.168.169.2
NAT Device:
192.168.169.2 (DHCP & DNS are enabled)
VNet NIC on host machine (VNet8):
IP 192.168.169.1
I got quite a lot similar issue report from google. Someone said the host machine even is not pingable. But I found it's just due to the firewall setting. I can ping 192.168.169.1 and even outside network such as www.google.com. So using tracert, it appears the routing is ok. And not only ping, all other UDP connection is ok such as my IM can login and chat with others
I also found a related issue article about the unidentified network http://communities.vmware.com/thread/85154?start=0&tstart=0. I've follow the article to remove the VNet NIC from unidentified network category. Actually I even shutdown all Windows firewall. And for guest OS, I tried both WIndows XP & Ubuntu. Neither worked on TCP.
Some article mentioned Internet connection sharing. I tried but doesn't work either. And in face I don't need internet connection for I even can't TCP connect to the host machine.
I'm sure there should be some similar issue reports in this forum but now the forum search seems down. And I'm not sure if there's already a solution to this or it's just some limitation of VMWare in certain circumstances.
Thanks for the help in advance.
