I'm replacing a Draytek 2820 with a new RB1100AH (very exciting) - The Draytek 2820 simply has four ports at the back, which are all switched. Our network is currently flat, same subnet, no VLANS etc.
On the RB1100AH, each port is independent (by design, of course) but for the moment, I just want it to behave like the 2820 - so aside from the WAN1 and WAN2 on ether1 and ether2, I can just plug in to any port.
Is the 'correct' way to go about this to just designate ether4-13 as slaves of the ether3 master?
Is there a better way that I'm not perhaps aware of?
I understand that normally one would just use an unmanaged/managed switch for this, but it seems a waste with all the GigE ports already there.
For a frame of reference, the 1100AH will be acting as firewall and gateway/NAT, with dual WAN interfaces.
