I have setup the bridged networking in OpenSuse 11 host using the instruction in the manual. I can connect to the Internet from the Windows XP guest.

The guest has DHCP setup for the IP. On the host:

br0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
inet addr:192.168.1.101 Bcast:192.168.1.255 Mask:255.255.255.0

eth0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
inet6 addr: fe80::xxx:xxxx:xxxx:xxxx/64 Scope:Link

vbox0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
inet6 addr: fe80::xxx:xxxx:xxxx:xxxx/64 Scope:Link

I was able to ping6 to vbox ipv6 address from host. I cannot ping6 from Windows XP to eth0's ipv6 address.

Please tell me what is going on? Is it a good idea to disable IPv6? If so, how?

I have disabled firewall on the guest to test this out.

I have resolved this problem. It works the way it is. I can telnet the host (if I disable the host firewall) using 192.168.1.101 IP address. The host can also telnet the guest using the guest's IP address. So it seems to work now.

My remaining problem is that if I disable the firewall, then I can connect to the host machine (telnet) from the guest. However, if I enable the firewall, then I can't telnet. Ping still works from the guest to the host.

This machine uses the default firewall. In Yast, I set the br0 interface as internal zone, and same thing.

I also follow advise from:

http://en.opensuse.org/Bridging

Stop firewall then
Edit this file: /etc/sysconfig/SuSEfirewall2

add this line:

FW_FORWARD_ALWAYS_INOUT_DEV="br0"

and change this line:

FW_FORWARD_ALLOW_BRIDGING="yes"

Then start the firewall again. Same problem.

Please help.
