Hi all, I'm observing an issue that as soon as libvirt starts, UPD broadcasts going through physical network (and unrelated to any virtualization) get broken. Specifically, windows neighbourhood browsing through samba's nmbd starts suffering badly (Samba is running on this same box). At the moment I'm running a quite outdated version 1.2.9 of libvirt, but other than this issue,

Hello guys I don''t know if this thing has been posted before (if it was , please forgive me). I have 7 computers at home and I want all of them to have access to the internet.

The other computers have ips ranging from

Dear list members, Masquerading does''not work for me. This is a Mandrake Linux 10 system, but I use another kernel, that included in the original distribution (original: 2.6.3, now used 2.6.8 because of a lot of suck with OpenSwan with kernels prior 2.6.4). The problem seems to be similar or identical mentioned here:

More details : I noticed that every start of xend is adding the POSTROUTING masquerade iptables rule, and nothing is done at stop time.

Hi all, I'm currently in the process of building a 2-Node libvirt/KVM Cluster and ran into some issues regarding the network connectivity of our virtual machines.

Then we tried microsoft.com to download some Windows iso images from MS Partner Network. The page

Here is the config. I''ve two links to outside via two

Okay here is my setup: Gentoo Box running 2.6.4 w/ 4 NICs 1 NIC is for internal network 3 NICs are for external network The machine has a static address assigned to the internal network nic. This nic runs dhcp and dns forwarding. The other 3 nics have external dynamic IP addresses. All will have the same gateway.

Thanks for the reply! output: net.ipv4.ip_forward = 1 What do you mean "The out:any and" Anywhere else I can look as to why the connection isn't going? Do I need some kind of listener at that port on the host? I'm not even seeing the packet count on the prerouting chain increase when the connection attempts are made.
