Hey all,
>From all the manuals, faqs, howtos, etc. It looks like I have everything configured correctly and everything but the networking is working. Can anyone suggest what I might have wrong?
On the network the host and anything on the actual network can ping the guest VM. But the guest VM can't ping the host or anything on the network nor can it connect to anything on the network.
There is no firewall running on the host or the guest VM.
Form all the reading I have tried setting the below.
net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0
/proc/sys/net/ipv4/ip_forward=1
/proc/sys/net/ipv4/conf/all/send_redirects=0
Below are all the outputs that I could think of getting. The host is 64bit and the guest is a window 7 64 bit. I don't have the ipconfig from the windows but it is set to 172.16.0.205/24 on local connection 1 shows the same mac address as vnet0.
