[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-users] Xen DomU with 2 interfaces LAN & WAN with dummy
Hi,
First post here so a BIG Thanks to dev-team & Co for open source.
Sorry for my poor knowledge in english...
The problem : My physical machine ( 2 interfaces : 1 LAN, 1 WAN ) as a public IP
outside the public ip's pool of my DomUs.
I can reach the LAN, but not the WAN.
I run a Xen Dom0 on a debian etch ( core duo ).
I have :
-1 public IP like this :
212.212.52.26 with gateway 212.212.52.25, network 212.212.52.24 and
212.212.52.27 as broadcast address.
-1 /29 pool like :
212.212.35.224/29 so 212.212.35.224 as network address, 212.212.25.231 as
broadcast address.
-1 LAN network 192.168.2.0/24
on Dom0 :
/etc/network/interfaces :
allow-hotplug eth0
iface eth0 inet static
>-------address 212.212.52.26
>-------netmask 255.255.255.252
>-------network 212.212.52.24
>-------broadcast 212.212.52.27
>-------gateway 212.212.52.25
allow-hotplug
iface eth1 inet static
>-------address 192.168.2.54
>-------netmask 255.255.255.0
>-------broadcast 192.168.2.255
auto dummy0
iface dummy0 inet static
>-------address 212.212.35.225
>-------netmask 255.255.255.248
>-------broadcast 212.212.35.231

i have created a script called by xend-config.sxp with :
#! /bin/sh
"$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=XenBrWAN
"$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=XenBrLAN
Thats it. I can join the LAN, but not the WAN. with netdev=dummy0 and not
netdev=eth0, xen create a pdummy0 and it s the same.. i havnt internet connec.
'(
Any idea please fellows?
Merci !
