I only found the following five manuals on their FTP site:
ftp://ftp.us.zyxel.com/P-660H-T3/document/P-660H-T3_v3-40_UsersGuide.pdfftp://ftp.us.zyxel.com/P-660HW-T1/document/P-660HW-T1_v3-40_UsersGuide.pdfftp://ftp.us.zyxel.com/P-660HW-T3/document/P-660HW-T3_v3-40_UsersGuide.pdfftp://ftp.us.zyxel.com/P-660R-T1/document/P-660R-T1_v3-40_UsersGuide.pdfftp://ftp.us.zyxel.com/P-660R-T3/document/P-660R-T3_v3-40_UsersGuide.pdfHowever they are all huge PDFs and would take all night to download on my connection. And I suspect they all pertain to T1-3 connection models.
You need to know exactly what model modem/router you have and whether sprint has loaded a custom firmware on it...
Your ISP's online help does not seem to indicate that they have provided you a modem/router that is capable of port forwarding. (or do not allow you access to it.) It seems that sprint has handed off their DSL to embarq:
http://www.embarq.com/support/hsiuserguides.html#modemhttp://www.embarq.com/support/guides/CPE/660/660dhcp.pdfhttp://www.embarq.com/support/guides/CPE/660/660static.pdfhttp://www.embarq.com/support/hsiuserguides.html#router(no 660 links)
Again more PDFs... I'm really learning to hate pdfs....
You'll need your ISP to tell you exactly what equipment you have and if they have done anything to it or whether its stock ZyXEL gear (unlikely, zyxel's specialty is custom firmwares for ISPs).
This is a bad sign:
Zero Configuration
The Prestige 660's Zero Configuration technology allows users to hook up a DSL connection without hassle. The user-friendly design embedded in the gateway is OS independent and supports all kinds of operating systems in the host PC.
Also a bad sign:
UPnP Support
UPnP (Universal Plug-and-Play) makes connecting PCs of all form factors and intelligent home and office appliances easier and even automatic by leveraging TCP/IP and Web technologies. The Prestige 660 series supports UPnP discovery and UPnP NAT Traversal and can automatically solve many NAT unfriendly problems.
Oh its all coming back to me now.... Zyxels javascript horny site will not work properly in Firefox... the selects only work in IE...
Zyxel lists the following P-660 models:
P-660H-61
P-660H-63
P-660H-67
P-660H-D1
P-660H-D3
P-660H-T1
P-660HW-61
P-660HW-63
P-660HW-67
P-660HW-D1
P-660HW-D3
P-660HW-T1
P-660HW-T3
P-660M-61
P-660M-63
P-660M-67
P-660R-61C
P-660R-63C
P-660R-67C
P-660R-D1
P-660R-D3
P-660R-T1
P-660R-T3
P-660RU-T1
P-660RU-T3
We can probably rule out the T1 or T3 models or we wouldn't be having this discussion.
That leaves:
P-660H-61
P-660H-63
P-660H-67
P-660H-D1
P-660H-D3
P-660HW-61

P-660HW-D1
P-660HW-D3
P-660M-61
P-660M-63
P-660M-67
P-660R-61C
P-660R-63C
P-660R-67C

What connection speed are you paying for on your account? Embarq lists the following options:
Starting at $24.95: up to 1.5M download/384K upload - Excellent for basic home internet access needs including music downloads, stock trading, shopping online and casual browsing.

Starting at $44.95: up to 5.0M downloads/640K upload - Ultimate speed option for online gaming, and anyone requiring the most intense usage.
This will help us establish what model modem/router you have. Though the ISP should be able to tell you, but we all know how call centers are staffed...
I hear Roadrunner down in the states is pretty good.
The other alternative is to buy your own DSL modem (if the ISP will allow it) and seperate linksys router.
Though the one you have may have the capabilites required for a real internet connection, we still don't know yet...
