SMC Router Problems

[swashbuckler]

I have 3 comps
1 hub, 1 router, 1 adsl modem

2 comps are hooked up to the router (one is win98 other is xp)
1 comp hooked up to the hub, its winxp (yes i know i dont need it hooked up to the hub, but thats part of the problem)

NIETHER of the comps can transfer files to each other, connect to each other over a LAN, or PING each other

I have no idea why, they are all on the same ISP
cept 2 are on a router and 1 is on the hub
a diagram of my setup is here

I have the ROUTER's firewall turned of....
when i run IPCONFIG on the winxp comp HOOKED up to the hub
i get this

Connection-specific DNS Suffix . : my.host.isp.net
IP Address. . . . . . . . . . . . : 142.59.54.22
Subnet Mask . . . . . . . . . . . : 255.255.248.0
Default Gateway . . . . . . . . . : 142.59.160.1

on the computer that has win98 thats connected to the ROUTER
says this from WINIPCFG

IP ADDRESS: 192.168.2.101 (that IP is not a IP from my ISP.. my router makes it like that)
SUBNET MASK: 255.255.255.0
DEFAULT GATEWAY: 192.168.2.1

my other computer running XP which is also connected to the ROUTER says something like this

Connection-specific DNS Suffix . : blank
IP Address. . . . . . . . . . . . : 192.168.2.149
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.2.1


thats all i really know...plz help

It appears that XP machine hooked to the hub is getting the public IP and leaving the others with nothing. This wouldn't be possible if the router was doing what it's default configuration is. Have you checked the settings in the router's configuration? Usually you do that by typing the IP of the router in your browser (192.168.2.1) and logging in. What are the settings there?

[swashbuckler]

well there's many directories in the settings, which part do u want? NAT? LAN? ?

Are you sure you have the diagram of your network setup correct?

Judging by the IP configs you posted. I would have said your ADSL modem is plugged into the HUB, your Router WAN is plugged into the HUB, WinXP (142.59.54.22) is plugged into the HUB.

Both computers WinXP (192.168.2.149) and Win98 (192.168.2.101) is plugged into the Router. These 2 computers should be able to ping each other and the router (192.168.2.1). Both computers and the router is on the same subnet.

I'm assuming you can access the internet on all 3 computers?

Please double check your configuration.

Technician,

You would obtain this result with the network configured as shown.

Swashbuckler,

Throw out the hub.
Connect only 1 PC for the moment to the router. Nothing else.
Go to the web setup page at 192.168.2.1 Enable the Firewall, Gateway mode, DHCP. Place the XP that used to connect to the hub in the "DMZ" zone at IP 192.168.2.2

Plug all three computers into the router. The other PCs should be configured with automatic addressing.

If you need static IPs start the range from 192.168.2.2 -- 192.168.2.100, to avoid the DHCP range.

Place the XP that used to be connected to the hub at 192.168.2.2, 255.255.255.0, with a Gateway of 192.168.2.1, and a DNS setting of 192.168.2.1. This will give it firewall free access to the internet without using the hub approach.

Turn off the router and all PCs.

Turn on the router. Turn on the PCs.

bcastner

so this will make me able to ping and transfer files and play on a LAN with all 3 computers?

 

[swashbuckler]

oh and i forgot i have this router

[swashbuckler]

wait, the aDSL is directly connected to the hub, then the hub connects to my computer (winxp) and then it connects to the router which connects to the 2 other comps

sorry for the mistake i made...

http://mxg.darkexile.com/prob.JPG

i updated the diagram

 

[vickero007]

That's the problem. Lose the hub and connect everything to the router. Connect the router to the ADSL modem. Set it up as bcastner said (DHCP, Gateway, Firewall) and reboot it. Do the configuring from one pc then when it is working hook the others up and boot them up.

Swashbuckler,

You can ping and have LAN connections. The only possible thing about pings is that some routers will suppress ICMP traffic from the WAN side of the router to the LAN side. There is usually a setting on the Web Page of the router setup to block or disable such traffic. You can permit the traffic if you would like.

 

[swashbuckler]

Enable Gateway mode, DHCP...well how do i enable GATEWAY mode?, i know how to enable the firewall, and i think i no how the enable the DHCP server

"Place the XP that used to be connected to the hub at 192.168.2.2, 255.255.255.0, with a Gateway of 192.168.2.1, and a DNS setting of 192.168.2.1. "

in the DMZ settings there is only two places to put things:
Public IP Address and Client IP Address
client Ip address has only one part to fill in, the end of the IP, looks something like this


192.192.2._
192.192.2._
192.192.2._
192.192.2._ (where _ is any number u want)

Public u can fill in all the parts of the ip
they all say:
0.0.0.0
0.0.0.0
0.0.0.0
0.0.0.0 etc

so i dont really understand
"Place the XP that used to be connected to the hub at 192.168.2.2, 255.255.255.0, with a Gateway of 192.168.2.1, and a DNS setting of 192.168.2.1. "

because you mentioned 4 parts to place the numbers, where do they all go?

thanks

 

[vickero007]

About "Place the XP.." bcastner is saying to go to that computer. Right-click Network Neighborhood, choose Properties. Highlight TCP/IP and choose Properties. There is where you type in all of that information.

Do you want 1 computer outside the router? If not disconnect them all. Connect the router to you ADSL modem. Connect one PC (preferably the one with the 142.59.54.22 ip) to the router. Reboot the cable modem and then the router. Now check the IP of that computer hooked to the router. If it is still 142.59.54.22 or 142.anything then do ipconfig /release. Now do ipconfig /renew. Try to browse the internet. If you can just hook up the others and go to their TCP/IP Properties and set them to Dynamically receive IP.

If ipconfig /renew doesn't work. Open up your browser and type in the IP of the router (192.168.2.1). Log in and make sure that it is set up as a DHCP server.

ok so far this is waht i think i shood do

the one comp with WINXP that was already hooked up to the router (the downstairs comp) has all the 192.168.2.1 login setup (not the 142 one im on right now), so I want to use that computer to configure the router.

So I shood take away the hub
Hook the aDSL directly to the router,
unplug all computers cords from the router
hook the WINXP downstairs comp up to the hub
login to 192.168.2.1
enable firewall
enable THIS COMP as A DHCP Server
enable this comp's gateway mode (how do i do that??)
SAVE
plug in the computer i use with windowsXP to the router (the 142 one)
plug in the windows98 one into the router
turn off the router
turn off all 3 computers
turn on the router
turn on all comps
??? this about right? if not please edit the steps i made thx

 

[vickero007]

Yes but the router will actually be the DHCP server and gateway, not the computer. This would allow you to hook any computer to it (via the hub or not) and get an IP automatically. Try it and let us know. We were under the assumption you wanted a computer outside of the router (in DMZ) but if that's not the case this way is the way to do it.

well i want to be able to play games on servers around the world on all 3 of my comps, and i want to be able to play together with the comps like a LAN, so for this is DMZ required?

 

[swashbuckler]

because i remember awhile ago I had all 3 comps on the router, the net worked on all of em, but all game ports were blocked, and i tried openening them in the options but it didnt seem to open the ports...

 

[vickero007]

You may have to disable the firewall in the router to play, I don't game so I don't know how that works. You may have to just use the hub and share the internet through one of your computers (the one you game with).

-Volkoff007

 

[swashbuckler]

I thought DMZ would cover gaming, isnt that what BCASTNER said
"This will give it firewall free access to the internet without using the hub approach."

 

[vickero007]

It will, but most DMZ's are done by using multiple (at least 2) public IP's. The DMZ is a logical area where both the outside and inside can access because it sits between 2 networks:

| Home Network | Router&Firewall | DMZ | Firewall | Internet

This allows companies to put their webservers in the DMZ so they can be accessed from the outside through the firewall that is secure, but not as secure as the next one in. This way if the web server is compromised the local network is safe.

In your case if you want all of the 3 pc's to be able to access the network and have one on the outside of the firewall then you won't be able to use the router's NAT function (which is how you share Internet). You may be able to set it up so the one computer uses Internet Connection Sharing (ICS) to share the connection with the other 2. You could then protect the other 2 with software firewalls as long as that wouldn't prevent the ICS.

Let us know if having all 3 behind the router doesn't work. You may have to set a rule in the router's firewall to open certain ports (for gaming). If this doesn't work you could try the other option.

i can have 3 comps in the router and they can surf the net, but ports are closed, and they cant connect
