I would like to know, what is the difference between Gateway and Router operation modes. The WRV200 when switched to the Router operation mode appears to stop its Gateway operations. As, the LAN devices are loosing Internet access in such a case. But, is it all what this switch does? (Except for enabling the dynamic routing feature, that is) In the Router mode the routing table does not change. So, I see no reason for the internet access to be stopped. Unless, the NAT is switched off.
