I'm replacing our office's Draytek 2820 (Dual ADSL) with a RB1100AH. We have a simple 'flat' network (same subnet, no VLANs etc), with a couple of external sites on different subnets VPN'd in, but we don't need constant connectivity so it's ok for me to tinker.
The draytek 2820 simply has 4 ethernet ports, which are all switched. I have these going to another unmanaged (but only 10/100) switch, which goes to all the clients, wifi, etc.
I want to initially replicate this setup on the 1100AH. Is a port switching group the right way to do this? To clarify, I basically want the ethernet ports to behave as a single switch, with the exception of the two WAN interface ports.
Would the best way to do this be to just designate ether4-13 as slaves to ether3? Is there a better way to be going about this, given what I want to initially achieve? If it is suggested that I purchase a gige switch, I may do that, if it will make life easier in the future.
