Bridged networking on openSuSE 11.4 with Xen ...
 
Newbie Question:

How do I setup networking on openSuSE 11.4 on an HP Proliant DL385 G7 with 4 NICs to host Windows 2008 R2 on Xen?

I've installed openSuSE 11.4 with all the patches (and most of the server patterns - Mail and News, LAMP, LDAP, Samba, etc.), and I've installed Windows 2008 R2 in a Xen virtual machine. I'm having problems configuring the 4 NICs

eth0, eth1, eth2, eth3 are "bound" without an ip_address as br0

eth0 connects to my ISP - currently through a private LAN - It connects directly to the router with static IP 192.168.0.105

Eventually, one of the other NICs will serve ip_addresses via DHCP to a separate LAN (for use in an office setting), and eth0 will be set with a static IP from the ISP That means, eth0 will be static to the ISP, and the other NICs will attach to a switch serving private ip_addresses in the 192.168.0.xxx range.

Currently, I have br0 unconfigured and eth0 static.

I have configured eth0 in the External Zone and br0 in the Internal Zone in the firewall, and all the correct ports are opened (afaik) I have enabled masquerading. Hostname, Domain (workgroup), DNS Server addresses and IPv4 Gateway are configured.

Windows 2008 R2 (Guest VM in Xen) "sees" the other machines on the network, and "browses" the internet, although it will not download patches except intermittently. I have not tried connecting to it from the LAN Eventually, I wish to run Windows Terminal Server.

openSuSE cannot "browse" the internet, though it initially did.

What am I missing? I "think" I need routing or NAT, or I may have my bridge setup incorrectly, although I've tried almost every combination.

Google says Xen should be setup with either NAT or a Bridged Network.
