Configuring Router

[abu_has_the_power]

ok, i got a us robotics router. now, i go into the config thing, and into virtual server. in the instructions on their site, it says:


Port forwarding sets up public services on your network. When Internet users make requests to a specific port in your network, the Broadband Router will forward those requests to the appropriate computer. The computer must be configured to a static IP address to use port forwarding. Port forwarding is generally used to set up a Web server, ftp server, or e-mail server on your network. Some well-known services are included in a pre-defined list.

do i have to use static ip? cuz i'm not sure if comcast is static or dynamic. now, i do this:


To add a server using Forwarding, perform the following steps:

Enter the port number and the IP Address of the server that you want to allow Internet users to access.
Configure as many entries as you want until all the entries are filled in.
Click Save in order to save the settings.

For example, if you have an FTP server (port 21) at 192.168.123.1, a Web server (port 80) at 192.168.123.2, and a PPTP VPN server at 192.168.123.6, you need to specify the following virtual server mapping table:

and i have 6881-6999 in the Service Ports and Server IP is my router's ip. i go into bt, and it still in yellow. anyone wanna help here?

and btw, where do i get a firmware upgrade for this router?

When they "static IP", they mean static on your LAN. Like, your web server will always have the IP address 192.168.0.5 on your LAN.

Not sure about the rest...

a little help on this please?

[abu_has_the_power]

can&#39;t anyone help? clocker? lynx? people? anyone? i need this router to work. now that i have a router, i want the protection, and the bt usage

the router can use a dynamic IP, so you can go ahead and set the router as dynamic. in order to do port forwarding, you have to set the PC&#39;s ethernet card (in Windows, under Control Panel -> Network Connections -> Local Area Connection -> Properties -> Internet Protocol -> Properties) to use a static LAN IP so it will have the same LAN address every time it boots up-- port forwarding will not work without this, because the router has to know which computer to forward the ports to.

the router&#39;s manual should tell you what LAN IPs and subnet mask you can use. the first three numbers will be the same on all of your PCs (like 192.168.0.____ or 192.168.254.____)... and then you just fill in the fourth number with whatever you want, like 1 or 2 or 3, but each PC has to use a different one. the subnet mask will probably be something like 255.255.255.0. you can look at your PC&#39;s LAN IP first, and see what kind of address the router was automatically assigning to it, then use that as a guideline. the main goal is just to make sure that the PC gets the same LAN IP every single time, instead of letting the router assign a random one.

the router config may require you to add an entry somewhere for each PC, after you set their LAN IPs, so that you can select them as the "owner" of the ports.

thanks a lot man. now, what do i put for default gateway?

[3RA1N1AC]

the default gateway is the router&#39;s LAN IP. it&#39;s whatever address you typed into your browser to access the router config.

i just did this, and i couldn&#39;t browse any website at all. did i do something wrong?

i switched back to dynamic to get back online

[3RA1N1AC]

were you still able to access the router configuration, after setting the PC&#39;s IP? the change might not work right away... you might need to reboot or at least disable then enable the ethernet connection under Windows, before it can acquire the new IP.

like i said, you should leave the router itself set for dynamic IP. it&#39;s just the PC that needs a manual IP.

my ip in the status window starts with: 12.250.#.#

is that rite?

no. i tried to get in, and it said #.#.#.100 is logged in

[3RA1N1AC]

your PC&#39;s IP starts with 12.250? that doesn&#39;t sound right. the standard LAN IP starts with 192.168 because there are no internet sites that use that address-- it&#39;s reserved for LANs.

but this is prolly the easiest way-- just let your PC get a dynamic LAN IP from the router. then check the status, copy down all the numbers (IP address, subnet mask, and default gateway), and then enter them manually exactly as they already are. if it works now, you may as well just keep that address.

then boot up your other computers and do the same with them. just make sure the final number of each PC&#39;s IP is different.

when i do all this in properities, and i restart my pc, no websites get loaded up. :unsure:

in the status page of the config, i get a wan ip and wan gateway and stuff. do i use that? i know wan is wide area network. does that apply to my at all? and it starts with 12.#.#.# etc. i&#39;m guessing that&#39;s not wat i&#39;m supposed to put into the network settings from control panel.

god i&#39;m so confused

[abu_has_the_power]

http://www.usr.com/support/8000a02/8000a02-online-manual/images/login.gif

here&#39;s wat my status window looks like, but with # in each of the boxes. the IP Address and Gateway all start with 12. and #.#.#

is that wrong?

[abu_has_the_power]

and also, this thing is enabled:
http://www.usr.com/support/8000a02/8000a02-online-manual/images/confutility12.gif

it says in the manual:


DHCP Server: You are given two options: Disable and Enable.
Range of IP Address Pool: Whenever there is a request, the DHCP server will automatically allocate an unused IP address from the IP address pool to the requesting computer. You can specify the starting and ending address of the IP address pool.
Domain Name: This information is passed on to the LAN client.

does that have anything to do with this?

[3RA1N1AC]

yeah the PCs shouldn&#39;t be concerned with the WAN IP, when you use a router.

sorry, i&#39;m prolly not explaining this totally clearly. different routers all have slightly different ways of doing things, so it&#39;s kind of hard to give 100% correct advice without owning that model.

and btw, i only have 1 pc connected to the router rite now. will that affect anything?

[3RA1N1AC]

nah, doesn&#39;t matter how many PCs you use.

okay, i&#39;m looking at the u.s. robotics page.

does your config page still say this?
http://www.usr.com/support/8000a02/8000a02-online-manual/images/confutility4.gif
the router&#39;s default LAN IP is 192.168.123.254. the "pool" is the range of fourth numbers that the PCs can use, and the default range is 100 to 199.

the router&#39;s LAN IP should be 192.168.123.254, and the PC can be anything between 192.168.123.100 and 192.168.123.199. 192.168.x.x are internal network addresses only, so it&#39;s okay to discuss them specifically-- people cannot access them from outside.

i gotta go. i hope you figure it out, though.

[abu_has_the_power]

omg&#33;&#33; i got it to work&#33;&#33; i had to fill in the 254 thingy in prefered dns&#33; now it works&#33;&#33; ok, now wat do i do after i get this static ip thing going?

[4play]

he router&#39;s LAN IP should be 192.168.123.254

its pretty standard to have 192.168.0.1 or 192.168.123.1 in your case as the gateway ip adress.

[abu_has_the_power]

thanks a lot guys. now, after i get this static ip thing goin, wat next?

[abu_has_the_power]

HOLY SHIT&#33;&#33;&#33; I&#39;M GETTING GREEN NOW&#33;&#33;&#33; WAHOOOOOO... GOD BLESS THE WORLD&#33;&#33;&#33; I&#39;M DA HAPPIEST COW IN THE WORLD&#33;&#33; :w00t: WAHOO&#33;&#33;&#33;

[abu_has_the_power]

so now my hardware firewall is set up rite? do i need to configure anything else?

[3RA1N1AC]

under miscellaneous items you might want to enable "discard ping from the WAN side." that just stops the router from responding to unsolicited pings from the internet (i.e. if someone is just trying to check out your address at random and see if there&#39;s a computer present)-- it won&#39;t have any effect on your PC&#39;s activity.

so is there anything else i need to do? or is the firewall thingy automatically enabled?
