I currently use Speakeasy as ISP. I connect to a static IP via a Broadband Blaster DSL Bridge 8012-V. The Broadband connects to a SonicWALL SOHO Internet Security Appliance which provides firewall and NAT services. The Sonicwall connects to a 10/100 switch to which I connect various computers whose IP's are set to NATed[is this a word?] addresses supplied by the Sonicwall.
I intend to use the sonic.net supplied ZTE 831 Modem but I like to change one at a time. That is I would like to get Fusion from sonic.net and change Sonicwall to sonic.net supplied static ip address. If this works [thus verifying that the 'plumbing is ok' I will install zte 831.
Will Broadband modem work with sonic.net Fusion using static IP?
Broadband Blaster DSL Bridge 8012-V specs Brief Specs: Data Encapsulation Protocol: - RFC 1483 Multiprotocol Encapsulation over ATM Adaptation Layer 5 ADSL Line Interface: - ANSI T1.413 - ITU G.992.1 (G.DMT) - ITU G.992.2 (G.LITE) DSL compliance: ADSL1 (G.dmt 992.1, G.lite 992.2, G.hs 994.1, DMT T1.413)
Based on the specs that you posted for the Broadband Blaster 8012-V it does not support ADSL2 or ADSL2+. It should still work on a Sonic.net Fusion line, but it will probably limit the speed that you are getting.
For best performance you should switch to a modem that supports ADSL2/2+ (such as the ZTE831).
There is nothing wrong with doing it step by step like you are planning to do. -- Got some spare cpu cycles ? Join Team Helix or Team Starfire!
