On my hardware machine this seems to fix the problem :). But why does
bridge-nf-call-iptables influent source nat on an other interface? -
Shouldn't the source address always be translated when an output
interface is set (iptables -A POSTROUTING -o eth3 -t nat -j MASQUERADE)?

Thanks for you quick help.

Best regards,
Bernhard
