Firewall Throughput

What does firewall throughput apply to? If I have a 1Gbps WAN link, firewall rating of 25Mbps, and a ISP bandwidth of 15/105 Mbps, firewall configured to allow all LAN to WAN and only rules of WAN to LAN. So with these Parameters what does the 25 Mbps bottleneck apply to? just incoming traffic subject to firewall rules or all traffic?

iMac, Mac OS X (10.7.3), 2.7 GHz Intel Core i5, 4 GB 1333

It should apply to just incoming traffic but it will depend how well the rest of the router works if it can achieve your upload limit if both are running at full speed.


On a 105Mbps line using an old firewall is such a pity.. why not buy a decent firewall.. modern routers with SPI firewalls are not that expensive that will easily handle 105Mbps.

A firewall is usually enterprise level gear.. if this is a home you buy a router.


Router does protect your local network.. it will not have vpn and virus checking as the enterprise firewall does but then you don't need those things for home setup usually.


All you need is a router of recent manufacturer.. anything out there today can handle 100mbit with ease..


Apple routers are ok.. albeit from security point of view do lack a proper firewall.


But there are lots of wireless routers which work well with Macs and do have proper SPI firewall.


They will handle speeds now up to about 800Mbps.. although if you start using the firewall, QoS and other heavy cpu usage apps it will halve that speed.


See smallnetbuilder reviews and wan to lan throughput chart.

The netgear R7000 is top of the list.. the Asus RT-AC68U however is better all round router IMHO. Either of those have more than adequate firewall protection for your network.
