I have already set up a static IP and forwarded the ports I need in the modem. I just have a few questions to clear some things up.
First some notes: This is an XP desktop, only one computer using the modem 1.5mpbs DSL, PPPoE type connection (don't know what that means) I only use port forwarding for 2 things: Azureus and RevConnect (DC++)
1. This is a Speedstream 4200 modem. I have read that if they are NAT enabled, which I think this is, these modems basically act as routers as well (at least for hardwired computers). In my modem's interface, there is a section for NAT/NAPT with 4 options: both disabled, NAT enabled, NAPT enabled, or both enabled (concurrent - *Concurrent NAT/NAPT may be enabled for one interface only.)
Currently it is set to NAPT enabled, by default. Which one should it be for my situation, do I even need it? What does NAT/NAPT have to do with port forwarding, if anything?
2. Since I am forwarding only the specific ports I need, do I need UPnP? I have already set the UPnP and SSDP services to "Manual" in the XP Control Panel. I have also set Azureus and RevConnect to not use UPnP.
The modem has the following options, with the last one selected by default: Disable UPnP Enable Discovery and Advertisement only (SSDP) Enable full Internet Gateway Device (IGD) support
Which option should it be? What about in XP?
3. I set up my static IP using the guide on this site, but the guide doesn't say what to do about the settings in my modem. The modem still has DHCP enabled. Doesn't this negate the static IP in XP? So should I turn off DHCP in the modem?
4. In the "Host" tab of the modem, I have the following boxes: IP Address: IP Netmask: Default Gateway: or Use WAN Host Name:
Everything is filled in except Default Gateway. Instead, Use WAN is selected. Is this correct or should I put my Default Gateway address?
5. In the "Static Routes" section, there are not "Currently Configured Static Routes". I'm not sure what this means or if it's necessary. The word static is confusing me. Is there anything needed here?
6. When I set up my static IP using the info from "ipconfig /all", for some reason the DNS server address was the same as the Default Gateway (192.168.254.254). I'm not sure if this was right but I went with it anyway.
