Firewall/NAT impact on bandwidth? Firewall recommendation?
I have recently installed Fusion. I am in an old house, with old wiring. I am using sonic.net supplied ZTE-300 modem. I have added supplied sonic.net supplied ADSL filters to active telephone outlets. The modem is normally connected to a Sonicwall SOHO firewall which also provides NAT translation. Using the sonic.net speed test through the firewall I get download speed of approximately 3.3mbs. When I connect the computer directly to modem output, using sonic.net static ip address, I get approximately 4mps.
Is the degradation firewall, NAT or ?
I have used the Sonicwall firewall for 6 years and it is a trusted friend.
Is it time to move to something better?
What would be better?
Thank you in advance for any help.
I have heard of the Sonicwall products (mostly good things), but never used them.
According to the chart on their website some models (such as the TZ150) may not be fast enough for your connection:
Sonicwall TZ series
Since you are happy with Sonicwall, perhaps upgrade to a higher performance model ?--
