View Full Version : Pinky at a loss
I'm so tired of thinking about it, I mind as well say uncle and let all of you in on my insufficiencies :rolleyes:.
I can't get my workstation and webserver to talk with one another without routing through my cable modem (the two are connected to a Linksys switch). This slows down file transfers since it only allows for max upload roadrunner has.
I am using windows 2000/XP Professional (which is basically "pretty" windows 2000), set an alternative IP and subnet, but they refuse to talk unless it's through my cable modem.
I'd would think they would know they are right next to each other. If I need to get another pair of NICs (for a direct twisted pair connection) or router, let me know. I've about exhausted everything with my current setup.

Can you ping them from each other?
Are you positive that the subnet is set the same? I was having a problem one time and I had just switched a couple twos and fives around. Hard to see, though.

If you want 2 computers on different subnets to talk you need a router. Switches won't do anything for you

You're probably right, I had heard that w2k could address two ips simulataneously, but dunno if that was fact or fiction.
Yeah, double checked the subnet setup, it was matching.
Does the lack of responses mean that one or both of the prior posts are correct? I'm clueless. If I got to buy a router I'll do that, just need to know if there's a workaround first.
I probably would recommend a router and here's why
1) Your setup is fundamentally flawed, but it's not your fault. cable modems are not routers like dsl modems are. They are bridges, which connect you to a large network. dsl modems are routers which can route traffic. The difference, while infintismal to 99.9% of the people out there, in this case means the world.
If you slapped a router into your network so it looked like this:
Cable modem->router->switch->workstations/servers then you would have your router taking the ip address from your cable modem and providing NAT/port forwarding to the proper destinations. You could map your port 80 to 192.168.0.x (or whatever private ip addressing scheme you use) which is your web server. this would effectively cut off other traffic to this server, and it would not leave other computers hanging out in the world.
Now, you should use static IP addresses, NOT DHCP because you don't want your router forwarding ports to the wrong address if you reload and grab a different IP.
Lastly, if you want to connect to your webserver from your workstation BEHIND the router, you would type http://192.168.0.x and NOT the public IP address! You won't get through at all.
I hope this helps

That's good to hear; most of the time it is my fault.
Everything you said makes sense. How to I keep my dynamic DNS address updated? Traffic will be lost if the IP changes.
Thanks for the specific info. It will be very helpful when I get the router :).
Dynamic DNS servers? ACK! Are you sure they keep changing? I'm not sure...thinking.......
My conclusion is you might just have to manually change them every now and then. Your router will pick up the changes, however if you manually enter TCP/IP info you won't get the changes.

Try installing a Non-Routable protocol like NetBEUI.
That will allow communication that will not go out the cable modem.

NetBEUI gone bye bye in XP professional :(
I'm currently running pc's with NT 4.0, 98SE and Win2K Pro, all through a Linksys router and connecting fine!?
I did have some trouble initially, but set all my internal IPs static, and listed the IP for the linksys as the DNS server.
All runs fine with that config, 100 on the local network fast as roadrunner lets me on the net.
I know nothing about XP, but the ping result is definitely my first question!
Here goes folks.
I used to have ICS (internet connection sharing).
I had twisted pair cabling. I continued to use this twisted pair cabling with my new switch setup.
Therein lied the problem. Fortunately I had bough a clamp, 200FT of Cat5, and 30 adapters for $30 at the local computer show recently.
Consulted with Phiber while the forums were down this afternoon, and replaced the twisted pair cables.
No problems :)!!!!!!!!! 100 mbit transfer rates between PCs!!
Thought I'd add this to the database ;).
The old "I used a crossover cable when I should have used a straight-through cable" problem. IT will trip you up every time.

hehe
Would never had thought of it if my ignorance wasn't so blaring when talking with Phiber, he oughtright said "NO! You don't need twisted pair" after a minute of me insisting I was doing everything right... then I broken down and tried it :).
I'm lost again. Thought this was fixed, had it working yesterday...
It is still routing through my cable modem!?
I think the two talk through the switch fine when I disconnect the cable modem and they fall to the alternate ips/subnet I have setup.
This is rediculous, they're 2 inches apart but travel 20 miles through a slow network to talk?!
I'll be back to update this.
**Yep, they talk fine once I disconnect the cable modem, allow them to autodetect after about 1 minute.
**Connect the cable modem after having it disconnected and they talk independent of it. This is what I saw yesterday. Now to reboot and see if they autodetect after that.
**Rebooted PCs, back to square one.

Have you tried connecting to the other computer using the private IP?
this is confuseing me why does it have to go through a cable modem to trnasfer i think its the switch holding u back wiat
with Road Runner u get 1 IP how dcan u use a switch with 1 IP
and if u have 2 IPs then the computers woul.d have to go through the cable modem because they have seperate IPs and not LAN ips
i think i am making no sense talk to me on ICQ
Pinky, that's the difference between a router and your cable modem. If you have an internal router it will direct your traffic right to the computer because that's what a router does. Your cable modem is a bridge, essentially a port of a switch extended REALLY far so your traffic has to go to the router (way far away) and then the router will direct traffic back towards your other IP (server). Get a router and all will be well.

I'm beginning to see the dilemma now.
So Phiber -- There are 2 IPs, cable modem service here will assign up to 3 ips for you... so my PCs each have an IP on the roadrunner system (which explains why after I disconnect roadrunner the PCs talk).
I guess I'll have to break down and get a router :(.
Thanks again, I'm done pulling at my hair. Time to cough up another $100

then u need a router
because the computers are not actually in a LAN they are both just connected to the net thats why u need to tranfer useing the upload and stuff
once u get the router u can get rid of the extra u paying for the other IP also

Nah, they don't charge extra for the other IP.
Router will soon be a reality. I need to find out how much a router switch combo will cost first, then maybe resell my switch and get the combo.
Okay, this may be a silly idea, but: are both of your pc's using ISP provided ip addresses? Because if they are, that may be part of the difficulty.
And another thought: if you are still running one or more pc's multi-homed (two ips) what order are they binding in? A couple years ago I was having trouble getting my first attempt at networkin running correctly, and I had to change the order of my nics and the protocols' bindings.
Wanted to give this one last bump.
I'm unwilling to buy a router at this moment (I really need to, as a musician, get a better audio card as my next upgrade). I have curtailed my large file transferring between these PCs, and since I'm not making any money with my webserver, it seems foolish to sink money into it.
If anyone has any last minute thoughts... so far I follow what Rugby's said, and it appears I will indeed need a router, but then again I was still hoping there may be something overlooked or possibly a networking feature that someone knows about that I could activate in w2k/XP Po' to get these systems talking directly.
Thanks again for all the help thus far.
Just bought one of those D LInk routers from Amazon.com
I will be crawling back here for help I'm sure :).
I gave up, roadrunner is going to limit me to one ip. This won't work. I have lots of networking to catch up on since I have to route ports in order to get my dynamic IP updated automatically and proper port routing...
Pinky, read my sticky at the top and this thread:

This should show you how to set everything up.

Yeah, I paged through it a few weeks ago when I was first encountering all these issues. That's a very good synopsis. I will be using much of what you have in there ;). Thanks for taking the time to create it in the first place.
Plug and Pray worked. Got one of those (think it was their last one :)) D-Link DL-804 routers from Amazon.com (see cyber deals section).
Only thing I was PO'ed about was the inability to specify the port being routed to... had to run my webserver off port 80, and on roadrunner that can prove to be bad as they scan that port for folks like me... but the router may save me there, as well as Zonealarm for the sneakier scans...
Anyway, it seems to be working fine for now, if anyone knows how to specify ports on these things let me know (PM would be best).
**Firmware update solved the Port assigning issue. Thanks to Amedeo602**
