similar to: No DHCP on default network when guest has multiple interfaces

someone recommended that i should give br0 the same hardware address as eno2. I did that, and restarted the vm, and it still does not work. Here is my current host interface config: ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft

Hi, Can you show as the config of eno4? And can you diff the config of eno1 and eno4. Looks like there is a difference somewhere. Regards, Simon > > > This server is equipped with four nics

I should have what i want to achive. The server is intended as a host for VMs. Our network has multiple VLANs, and the VMs will be connected to different VLANS. The interface eno1 is for host traffic and eno2 is connected to the trunk port of the switch, making the different VLANS availabel to the VMs via the br0. I want to use a VLAN-aware br0, so that I specify in my VM config (on the host

Hello All, I'm trying to figure out why xen-utils-common 3.2 doesn't suport bridging on multiple interfaces. I've been digging around /etc/xen/scripts/network-bridges. And modified it so that during boot, when executed the script writes into /tmp/netbr file, but I commented out code that actually creates bridges. I discovered that this script is called three times during boot, I

I have an access-IProm my isp that I configured my eth0 with. And I also have an IP-range assigned from my ISP that will be used on my servers connected to eth1. The IP-range is routed thru the access-IP. This is how my configfiles look like. Internal everything seems to work but not external. /etc/shorewall/proxyarp #ADDRESS INTERFACE EXTERNAL HAVEROUTE

Hi All, If I have a vlan-Id on an interface with an ipv6 address, then I am unable to ping a real router. The problem is that the Neighbour Solicitation originated from the Centos machine is missing the Vlan-Id in the packet. Therefore a real router will drop such a packet. I have tried this with Centos 4.7 and with Centos 5.5 with the same result. If I originate the first Neighbour

Hi Parke, Thanks, no I had not run those commands, but after doing so, my VPN address is not visible.

Hello all, I am having issues getting my virtual network to work correctly. As of current, I have set up a virtual network with virt-manager, using the routed mode to forward network traffic. I have found guests can see/ping themselves, the host's virtual IP and the host's real IP, but nothing else. Guests fail to see any other device on the real network or the internet. My host is Arch

Hi !, I have this problem. On a Mandrake 10.0 server with all the updates (Kernel 2.6.3-15mdk, iptables-1.2.9-7mdk and shorewall-2.0.3a-1mdk), one of our internal users have to FTP some files to our external web server.
