IP behind Home network

cy · Post by cy » Sun Jul 07, 2002 8:26 pm

I m running a home network for 2 computer using Crossover cable. I m trying to run IIS (Internet Information Service) from my client computer which have IP 192.168.0.2 but i do notice that people can't connect to my computer using that IP, so how do i obtain an IP that ppl can access to my computer?

Example: Host computer has IP of 24.xxx.xxx.xxx, client has 192.168.0.2. And i want people be able to connect to my client using the 24.xxx.xxx.xxx or other way that can do it, just like running a ftp server from client computer.

Addition Information: WinME on host, WinXP on Client.

Thanks a lot in advance

The IP your second computer has is not an internet IP, it is the IP your LAN gives it.

If you run a server on the second computer, you can connect to it using the same IP as your internet connection, which seems to also be the same IP as your first computer due to more than once NIC, or USB connected modem.

I do understand that the 192.168.0.2 is the internal IP, but i also tried to connect using the internet IP, not working

Ack..any other suggestions?

Try checking your firewall. If your using NAT or anything that may need to be configured for servers.

i didn't install any additional firewall, also disabled the one on XP, so i dont' think there's any problem with my firewall.

You have to route all incoming port 80 traffic to the second computer. How you do that depends upon what software you are using for NAT.

If you intend to run IIS, be sure that you have ALL the patches for IIS and the operating system. If you don't your computer and other folks will be at risk.

I don't believe that Cogeco permits servers, and they may have blocked port 80.

Are you using ICS? What proxy/NAT software are you running? The way you forward ports depends on your answer to this question.

IF your ISP blocks port 80, there is little you can do.

Yep i m using ICS, ME on host, XP on client. About proxy/NAT, i don't recall installing any software, do i need them?
And for the port 80, i think first i need to get the port forwarded before i can see whether it's blocked right?

Here's what you need:

But, since you don't understand that ICS is doing proxying and NAT, you should give some serious thought to whether you can correctly install, configure, and safeguard IIS. The rest of us folks on the internet are depending upon you to do it right and not create one more fountain of viruses, worms, and trojans.

Sorry to be harsh, but my computers and my customers computers are still being attacked continuously by folks that installed IIS without the necessary knowledge.

I understand, but the main purpose of my sites just to upload the digital pictures and little things on, so it's gonna be a personal sites for my friends. Therefore the security is not a big concern for me right now, but sure, in case of some no life people trying to make it into a virus, trojan fountain, i'll look into security too, thanks

Kip Patterson · Post by **Kip Patterson** » Tue Jul 09, 2002 3:51 pm

Well, that seems to me to be pretty insolent. It isn't YOUR security that is of concern - it's the security of the other folk you will mess up.

Enjoy your new dial-up account.

Explain please.

I don;t want to speak for Kip but I was thinking the same thing. If your ISP doesn't allow servers on their network then they may ban you.

Separately, It is very easy to scan whole blocks of IP addresses for webservers and IIS is famous for being completely insecure. A comprismised machine running IIS can cause problems for everyone on the internet - can be used to attack and infect other machines or contribute to a denial of service attack. That means that you running IIS without knowing how to secure it is a potential threat to everyone on the internet. Look up "Code Red" on your favorite search engine and read up on the details of the virus.

Cheers,

ME host of some sort with an XP client?

(shudder)

Try this - Q271071 on Technet

That is only a start, but for IIS it is a must.

And what Kip is referring to is when your ISP shuts you down.

Kip Patterson · Post by **Kip Patterson** » Tue Jul 09, 2002 6:01 pm

I was referring to the likelyhood that your provider will shut you down for a violation of their AUP, or for running an infected server. If you do not properly secure IIS, it is likely to become infected and a source of viruses, etc, within minutes. It is not something you should install on a whim.

ok, I have a better view now. So instead of using IIS, i might just want to use some web hosting or even pay for one, since most of them are well secured, am i right? Also save me the risk of getting ban from ISP

Why don't you just fire up an FTP server? You can swap pictures and files that way. Plus you'll eliminate some of the overhead involved in serving web pages. You can also put FTP's on just about any port you feel like, so if port 21 is blocked you can switch it to something else. Serv-U FTP Server is my favorite so far. Good luck.

yep i have experience with FTP but u know, not everyone knows how to use FTP

Soporific · Post by **Soporific** » Wed Jul 10, 2002 3:51 pm

It's true not everyone knows how to use it, but as you probably know it's quite simple to learn. You can even send hyperlinks to enable an automatic login. It goes something like this: ftp://username:password@24.x.x.x

It will open up in explorer and look like the local file system folders. I know it isn't pretty, but it's a temporary solution. The other solution of getting web hosting is probably better if you don't mind spending 20 bucks a month or so and are familiar with HTML and CGI stuff.

yep..agree or i can even make it anonymous access. I think i'll just sign up one of the hosting, free ones for now just to put the pics up.

Soporific · Post by **Soporific** » Wed Jul 10, 2002 5:36 pm

Cool. If you find a decent one, post the link. I'd be interested in a free one that didn't have an enormous amount of pop-up ads.

does banner matter to you?

Soporific · Post by **Soporific** » Wed Jul 10, 2002 7:40 pm

Nope banners are fine. Mostly just the pop-ups I want to avoid. I haven't actively searched for a free hosting site, but most of the ones I seem to run across have atleast one pop-up, sometimes more on each page request.

Thanks,
