Hi again
I notice that when I set the second gateway, and try to save the changes, I get this error on zentyal.log:
2015/01/21 13:46:29 ERROR> GlobalImpl.pm:660 EBox::GlobalImpl::saveAllModules - Failed to save changes in module squid: Could not get lock for service: squid
Is this could be a reason that do not save the second gateway configuration???
Thanks for any help
