It would depend on your switch configuration. If the switch is set to untagged vlan 1, then you wouldn't need to tag "internal" in fact you would just use "Network 1" If the switch port is setup as untagged vlan 5 or untagged no vlan and tagged vlan 1 then "Internal" would work correctly.

[cid:image001.jpg@01CC5D8F.C6D3AF50] So I have two NIC in server NIC 0 for management and NIC 1 for server traffic. I set up virtual network Internal on NIC 1 which has a VLAN ID of 1, dos this meen that VLAN port on the switch mush have a TAG for Vlan 1. As I thought it was default VLAN of 1 was already on the switch and I couldn't get the server to talk on his Internal network at all. Maybe I need to be using a different VLAN ID that's not in use on out network already.

Just use Network 1 if that's all that is going to be used. If you plan on tagging vLans then you will want to setup a new connection as well as configure the switch-port for such. Joe From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Hamilton, Ronnie Sent: Wednesday, August 17, 2011 8:23 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Xen Server Issue All, I have set up XenServer on a single box for some testing of Access gateway VPX. I also have a server 2008 instaled. I have two NIC's with an extra ordered. I have NIC 0 set as management with IP address and this works fine. The second NIC I have plugged into our internal LAN, when I create a Network and select NIC 1 and then select this Virtual Network in my 2k8 server I cannot get network connectivity. When I select the Network 1 which is the built in NIC 1 directly all works fine. Seem to be going round in circles is this possible with XenServer and Xen Centre free edition.
