I would like to have a router with high cpu capacity, memory and should be able to handle around 2 gbps of total traffic at any time (in + out in all interface) Also should be able to have good capabilities of NAT, around 60000 ips to be natted. The router should have four gigabit Ethernet port and 2-4 10/100 Ethernet ports. What are your overall suggestions, like model and things. Can you please suggest which is the best cost effective product available? Suggest at least two models with features.
