I have a host machine with eth0 and eth1. eth0 is connected to the lan and eth1 is connected to the internet I am trying to bridge both interfaces in xend so that xenbr0=eth0 and xenbr1=eth1 following some documentation i changed (network-script network-bridge) to (network-script multi-network-bridge) in /etc/xen/xend-config.sxp then i created a /etc/xen/scripts/multi-network-bridge file in put #!/bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 "$dir/network-bridge" "$@" vifnum=1 netdev=eth1 in side. I restart xend, which seemed to create the xenbr0 and xenbr1 interfaces. I then editted the domU config file. I changed vif = [ ''bridge=xenbr0'' ] to vif = [ ''bridge=xenbr0'',''bridge=xenbr1'' ] eth0 and eth1 are created on domU and i was able to set the ip addresses for eth0 and eth1. i was able to connect to the domU host through the lan ip address assigned to eth0. but i can''t seem to connect via the wan ip address assigned to eth1. from inside the domU i have tried to ping other machines on the same wan subnet, but i get a "Destination Unreachable". I have confirmed that the ip address and the subnet is correct. I can''t ping the domU eth1 ipaddress from the dom0 eth1 ipaddress which is on the same subnet. which leads me to believe my xenbr1 is not being setup properly. can anyone help me with this?

just an update. Now I am sure my xenbr1 is note being set properly it is being bridged to eth0 I changed the domU''s eth1 settings from static to dhcp, and eth1 gets an ip from the LAN which is connected to the eth0 on dom0. so i guess my multi-network-bridge script is not working properly.

Ok i think i''m starting to understand the problem. my xen host has two network cards eth0 and eth1 the eth0 was configured with the local lan ip. but the eth1 was connected to the WAN but not configured. I had no reason for the xen server to have direct access to the internet. But i wanted to setup a domU on it that would have a reason to access the internet. which i have tried to do. The only time the domU''s eth1 worked properly was when the dom0 eth1 is assigned an ip address. currently i have assigned a bogus ip address to get the domU eth1 working. is there a better way to do this?

You might try just typing "ifconfig eth1 up" without an IP address.> Ok i think i''m starting to understand the problem. > > my xen host has two network cards eth0 and eth1 > the eth0 was configured with the local lan ip. > but the eth1 was connected to the WAN but not configured. > I had no reason for the xen server to have direct access to the internet. > But i wanted to setup a domU on it that would have a reason to access > the internet. > which i have tried to do. > > The only time the domU''s eth1 worked properly was when the dom0 eth1 is assigned > an ip address. currently i have assigned a bogus ip address to get > the domU eth1 working. > is there a better way to do this? > > TIA, > Tomoki > > On 7/31/07, Tomoki Taniguchi <tomoki.taniguchi@gmail.com> wrote: > > just an update. > > Now I am sure my xenbr1 is note being set properly > > it is being bridged to eth0 > > I changed the domU''s eth1 settings from > > static to dhcp, and eth1 gets an ip from the LAN > > which is connected to the eth0 on dom0. > > > > so i guess my multi-network-bridge script is not working properly. > > > > > > On 7/31/07, Tomoki Taniguchi <tomoki.taniguchi@gmail.com> wrote: > > > I have a host machine with eth0 and eth1. > > > eth0 is connected to the lan and eth1 is connected to the internet > > > > > > I am trying to bridge both interfaces in xend so that > > > xenbr0=eth0 and xenbr1=eth1 > > > > > > following some documentation i changed > > > (network-script network-bridge) > > > to > > > (network-script multi-network-bridge) > > > in /etc/xen/xend-config.sxp > > > > > > then i created a /etc/xen/scripts/multi-network-bridge file > > > in put > > > #!/bin/sh > > > dir=$(dirname "$0") > > > "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 > > > "$dir/network-bridge" "$@" vifnum=1 netdev=eth1 > > > in side. > > > > > > I restart xend, which seemed to create the xenbr0 and xenbr1 > > > interfaces. > > > > > > I then editted the domU config file.
