Hi,

    I'm dealing with a problem that the worker nodes that are

behind a NAT aren't able to reach outside from time to time. (ie: on a given moment I can ping an address name and immediately after I cannot: "ping: unknown host"). The NAT was configurated using the following: *nat -A POSTROUTING -o eth1 -j MASQUERADE COMMIT

     Please, any advice here would be appreciated.

What's in you /etc/hosts files? You need ip's and names in there for clients on the Lan. You will need a primary and secondary dns addresses in /etc/resolve.conf

Thanks, Patricia
