Can anyone tell me what the expected maximum WAN2-LAN throughput would be on a 2920 (non-VPN) with the DoS defence & URL content filter enabled?

I'm sure that I've read somewhere that throughput drops off with the firewall & CSM features enabled.

I'm planning on using this with a modem on a FTTC line (rated 80/20 - currently getting ~ 75/18).

Thanks

When had Virgin Media it did clocked 105 Mbps with the 10 Up VM was offering... (both) DoS & the default firewall was on (but never used the URL filtering if this will cost any issue) ... i am not any longer with them to say if will handle their new 120 speed
Use the wan 2 which is giga and also disable the other wan (1) if you are not using it because may stolen some CPU power if you going to clock over 100Mbps

I think it's rated at max 90mb/s...see

so if you already have the router then it should be fine there's always a. Bit of an overhead but don't expect the connection date to be exactly the same as the throughput.

It used to handle more but I guess as more features got enabled they had to drop the available through put. Hence my sad experience of a 2960 when virgin upgraded.
