Yes i do. I do get responses from google, yahoo, this site or any other alive website at all even if 1st ISP is disconnected physically.
You mean here that you get responses from any site from the utilities ping, if the first connection is deactivated? The syntax was ambiguous that is why I am asking.
It looks like the ping from ZS is working fine. Don’t worry about the arp error, this is normal.
Could you please post here the output of the commands
iptables -L -v
iptables -t nat -L -v
Also a screenshot of the NetBalancer page from the web gui would be helpful.
