What router models could you suggest for such architecture: Internal network contains approx. 350 hosts, we have a single internet connection to our ISP, it's 10mbps ethernet. In near future we will upgrade it to20mbps. I want set up two routers with DMZ between them, first of them wil be directly connected to our ISP (there will be some acls there, not many), second one will be connected to our internal LAN (nat, qos). I think about 26xx or 28xx series, will it be enough?
