![[image loading]](http://i25.tinypic.com/xm1tzm.jpg) people told me to set it to DHCP but i cant find it, whenever i try to add this, it says: ![[image loading]](http://i32.tinypic.com/ip5kpf.jpg) when i was strictly connected to my modem i can host easily, but now with router i cant, so id have to do something with the router right? anyone have a linksys that has made it host-able?   | ||

Most commercial modems actually do some rudimentary routing. So by default, it does NAT, filtering, maybe firewall, etc. Your Linksys router (seems to be a "wireless router" aka an AP + router combo) obviously also does routing and NAT itself. In a home network, generally you only want one device doing NAT, or else you need to do double port forwarding and icky stuff. What you want to do is disable routing features on either the modem or the router. I'd choose the modem. So go to the modem interface (may need to connect computer to modem by Ethernet directly to access this) and switch it to "Bridged Ethernet" mode or some such, to turn off its routing. If you turn your modem to bridged Ethernet, then you have to make your router initiate connection with your ISP (could have been the modem doing this before). On the Linksys, instead of Internet Connection type: Automatic Configuration - DHCP, you need to put in something else. It's probably PPPoE that you need (ask your ISP or check your modem first for user/pass for that). In any case, this connection refers to how the Linksys is connecting on the WAN (Internet) side. DHCP server settings in the bottom half of the page refers to how locally it's assigning IP addresses on your LAN. The DHCP thing you set at the top was telling your router to get an IP address on the WAN side itself from another device -- probably not what you want. edit: Actually, people usually suggest setting a static IP for your local computer on your LAN for port forwarding. This is because in the port forward page, you set up which IP the router should forward ports on. If you use DHCP locally to set up IP addresses and it changes which IP your computer has, then you need to change which IP you port forward to, so that it again matches the computer you're using. So who told you to use DHCP? If the person was really talking about the option at the top (router get DHCP-assigned WAN side IP address from modem), then that means the person was telling you to turn on the modem's DHCP server capabilities and have the modem negotiate the PPPoE stuff with the ISP...kind of weird and not like what I said above. Just to be clear, there are 3 ways to make this work: 1. turn off routing features on modem (bridged Ethernet mode), make router do PPPoE and port forwarding (recommended) 2. turn off routing features on router (make it a dumb hub/bridge), make modem (normal mode) do PPPoE and port forwarding 3. make modem do PPPoE, make router do routing too; have port forwarding on modem to IP of router, which does a different port forwarding itself to your computer (omg lol); puts up a double NAT | ||

Go to router web interface and put in the correct ports to forward to your computer's LAN IP address (should be 6112 UDP and TCP, or was it 6112-6119?). In the command prompt, type "ipconfig"--IP Address is your computer's IP address, and Default Gateway is your router's LAN IP address. 2. Turn off all firewalls that may be on your computer, including the native Windows Firewall and even some antivirus programs while you're at it to make sure that's not the problem. Once you get it working, you can turn them back on, see if it works, etc., set some "exceptions" or such so that it still works when it's on. 3. Make sure you don't have double NAT problem as described in previous post. Incoming packets when you're hosting will ask to reach your WAN IP address (IP address visible to Internet, not the local 192.168.x.x or 10.0.x.x etc.) and the port number 6112. So whatever device it is that holds your WAN IP address (would be the router in the modem as bridged Ethernet case, as the modem will simply pass through everything to the router) as gotten from your ISP will get the packet and have to figure out where to send it. Unless you configure port forwarding, your device won't know where to forward that packet to. | ||

You may have to configure both modem and router depending on how they're currently set up. What's your modem model number? Go to the modem configuration page and see what mode of operation the thing is in. If it's not "bridged", or "bridged Ethernet", etc., you'll need to make some changes. (report back what it says) On a side note, there's actually 8 versions of my old nemesis, the Linksys WRT54G. Actually, within the same version number, some have different internal hardware too. But that's all irrelevant here; all of them including most all routers on the market will behave the same way for our purposes here. -_-;; | ||

1. ill go to my modem and forward the ip address? but ive done that before i setup my router, its there. 2. i dont have firewalls on etc, never have. 3. i still gotta read through all that O_____O | ||

I'll put all the steps here and simplify them hopefully. Steps: 1. Go to modem settings, write down your connection type, user name/pass, login information for ISP, etc. Or if you have it written down already, great. If you don't know the password, ask your ISP. 2. Go to modem settings and turn its mode of operation (probably PPPoE connection) into "bridged" or "bridged Ethernet" mode. Whatever looks like a stripped-down mode of operation. Turn off DHCP server capabilities and anything that looks like it might restrict traffic. You don't need to set port forwarding here. 3. Go to router settings and select PPPoE at the top (or whatever it was the modem used to be set on). Input your ISP user/pass login information stuff. Go to port forwarding section called "Applications and Gaming" and then "Port Range Forward", and input port 6112 both UDP and TCP and forwarded to your computer's IP address. Go to the Security tab and uncheck "Block Anonymous Internet Requests". I forget if you need to uncheck any of the others. That should be it. Make sure you know the password for your connection to your ISP before you make any changes. If in fact your modem doesn't do any routing features (check your model online), there shouldn't be anything about a "bridged Ethernet" mode, etc. and you can skip step 2. | ||

Applications and Gaming -> Port Range Forwarding -> 6112 for port to open -> 192.168.2.8 for the network address (only the last box is open for you to edit) | ||

Router1 has an external WAN IP address, your "real" IP address visible to people on Internet, as gotten from ISP connection. Let's say Router1's exteral IP address is 69.43.199.32. Router1 also has an internal IP address that's different that is used for its LAN subnet (say 192.168.1.1). Router2 has an external IP address 192.168.1.2 that's different from it's internal (back end) IP address too, say 10.0.0.1. Both the 192.168.1.x and 10.0.0.x subnet or ranges of IP addresses are invisible to people on the Internet. So Router1's external IP is visible to Internet. Router2's external IP address is in Router1's internal subnet, and your computer is in Router2's internal subnet, say IP address 10.0.0.2. So you have two different subnets and NATs going on. For double port forwarding, you set Router1 to port forward the desired port to 192.168.1.2 (Router2's external IP) on its internal side. Then you set Router2 to port forward that same port to 10.0.0.2 (your computer) on its internal side. So when a packet comes in, it'll be for 69.43.199.32 : (port #). It gets routed through the Internet and your ISP to Router1. Router1 looks at its port forwarding and decides to send it to 192.168.1.2. Router2 gets it and decides to send it to 10.0.0.2, the final destination. | ||

Actually I just checked, and it just gives that error message if you try to forward any port to 192.168.2.0, 192.168.2.255, or the router IP address (basically those addresses are restricted to use). Just put in the port information first including a valid IP address and then click Enable, and it won't bitch at you. In fact, you might want to check if just doing that is enough to allow you to host games--it will or won't be depending on your modem and how it's set up. (i.e. step 1-2 may be unnecessary depending, as stated earlier) | ||
