Sanity Check: SG-2440 capable of 1Gbps WAN -> LAN?



  • The SG-2440 shouldn't have an issue with 1Gbps of firewalling/NAT throughput, correct? No VPN, IDS, etc.



  • Probably a question for sales? It depends on a lot of factors, but you're not going to get full GB. Ethernet overhead and standard frames will cut some off the top even before NAT and firewalling. I know they'll run a 500mb connection at full speed with an average of around 50,000 states without stressing the processor.

    We already have one that we're getting ready to replace with a more power x86 server. I get about 950Mbps with my AT&T provided router, but I'd like to have the nicer pfSense metrics.

    You will not be having a real 1 GBit/s as I see it right, and also not nearly 1 GBit/s throughput at the WAN Interface with that appliance!!!
    If you are not really using or must using PPPoE you could have more luck.



  • is ATT Gigapower considered PPPoE?  Or any FTTP connection?

    I think AT&T home internet, Gigapower included, uses certificate based authentication, which is the main reason access is strictly locked to their (non bridgeable :( ) hardware*  I do believe some providers (mostly not in the USA) use PPPoE.

    *not that the hardware can't do it, but AT&T doesn't permit it.

    No, it's uses 802.1X.
