ICQ and ICS

My wife's internet access is through my machine using ICS. She's using ICQ at her work and wants to install it here at home. From what I'm seeing in the connection preferences of ICQ, it doesn't look like it will work.

Anyone have any experience with this?
 
I don't think it will work, ICQ isn't Proxy/connection sharing friendly. (Or well actually it's the other way around, Proxies and connection sharing are nice to apps that want to establish direct connections to other systems)

ICS isn't a proxy software, it uses NAT (network address translation). As far as any computer using ICS is concerned, it's directly connected to the Internet (though some ports may be blocked). It should work, though you won't be able to receive files...ICQ works fine without any modification behind my Netgear RT311 router (a NAT device as well).
 
That's what I was afraid of. Now she'll want me set up her sister and who knows else on my ICQ. Super. I'll half to let her use my machine for who knows how long while they chat on endlessly about all sorts of drivel. Oh well.

 
i have used icq through a WindowsME ICS setup where the connection goes through the "server" computer and the other is the "client".

dont know about recieving files, but we were able to chat.
 
So you think if I set it up under the connection tab as "I'm using a permanent internet connection(LAN)" and then check "I'm not behind a firewall or proxy.

I think if I set it up as "I'm using a modem (or any other dial up device)", I will get time outs and such while my machine is connecting. I have dial-up here by the way.

I guess I can install it and try it. I can always un-install it if I can't get it to work.

I said "Proxy/connection sharing friendly".

Also if the RT311 is a NAT device then WTF are you using ICS for. The RT311 (assuming it really does provide NAT service, I don't know but you say it does), will handle the traffic much more efficiently/securely/quickly/etc....

That's how I do it...when using NAT (unlike proxy sharing), applications don't have to be set up to contact a proxy server.



<< Also if the RT311 is a NAT device then WTF are you using ICS for >>

???? I never said I was using ICS....I was just giving an example of another NAT device. All consumer DSL/cable routers (Linksys, Netgear, D-Link) use NAT. My router might be specifically programmed somehow to allow ICQ to work, so I'm not guaranteeing it will work with ICS....try it and find out.
 
I have a Netgear RT314 and it does provide NAT service.

then WTF are you using ICS for

Where did he say he was?

EDIT: opps...guess he already pointed that out 🙂

EDIT AGAIN: ICQ will work fine with ICS. Wife and I did it using Win98 SE, 2000 and using Sygate
 
Sry Sohcan I guess I missinterpreted this &quot;As far as any computer using ICS is concerned, it's directly connected to the Internet&quot;. I was thinking one cable/DSL connection using ICS, then you stated that you had a RT311, anyway my bad....sry.

And yes I can't imagine why any company would manufacture a Router without NAT service (although I'm sure some of the first and/or cheaper consumers routers didn't/don't), or why anyone would buy one.

Thorin
 
I have had no trouble using ICQ on a ICS client machine. I did nothing special to run it, it just works.
 
behind a NAT, remember to set your cilent gateway to server ip, and DNS to ISP's DNS (or anyother public DNS)
now your setup to go out as if the connection is on your machine.
No proxies are needed.
 
heh I have had questions like this for a while.. Internet connection sharing software. does the internet see only the server side? how does the server know which data to pass on to other computers (say there were more then one) if they are sent with the destination address of the server?

I'm guessing that routers are the same that way.. am I right?

I'm wondering, becuase at school, they use a computer with software running. My computer teacher calls the server the border manager. yeah it's definetly possible to run pretty much anything that uses the internet, as long as it can pull the data off your network (you know, ethernet or whatever you're running).
 
Soccerman: AFAIK, NAT software operates in the same way as a router. Routers, like switches, have routing tables that &quot;know&quot; to which port data packets are to be sent. Hubs, on the other hand, will transmit data to all the ports (which is why they suck in high traffic situations...it's similar to trying to read a message in a high-traffic chat room). Unlike switches, routers forward data depending on the network address. They isolate each LAN into a seperate subnet (the third octet in an IP address). Routers are therefore the only device that can share a single IP address among multiple clients in a subnet. The Internet only sees the IP of the server computer or the router.

Kind of confusing, but it works. 😉

I'm asking, if the INTERNET only sees one IP address (it has to, otherwise that IP address in your network would conflict with something else, and the data would be sent to another place on the internet :Q), THEN how does the router, know what IP (in the network) to send the data to? could it be based on MAC addresses as well? or is the extra data stored somewhere else in the packet, that only routers, or NAT software can decode?

yeah I know that stuff, it's just that, the internet CANNOT normally see the devices inside the network (unless you have alot of IP addresses that you paid for), if you have NAT software running, or a router running...
 
I have three computers sharing a DSL connection using ICS, no problem with ICQ at all. But we can't transfer files to each other through ICQ. Otherwise, everything seems to work fine.

you saying you can't transfer files from computer to computer on yuor LAN? or just anywhere?
 
Right now I have a DSL line with multiple static IP's, but in the past (until about six months ago) I had an ISDN line with a Netgear router doing NAT for me. I never had any problems using ICQ, including sending and receiving files on the network or on the internet. The only thing I couldn't get to work because of NAT was voice and video (like Netmeeting) because they use UDP instead of straight TCP. Don't know why other people are having problems with file transfer... I haven't.

Soccerman:

I just can't transfer files to the computers that are on my LAN. I can transfer to other people fine.

 
&quot;I'm asking, if the INTERNET only sees one IP address&quot;

Yes as far as any server on the &quot;outside&quot; of your router (NAT) is concerned all requests come from 1 IP, and the router Translates the packet addressing as the replies come back in.

Anyways, you CAN share files over ICQ on a ICS lan. Just, under the connection preferences, select I am using a LAN. Then select, I am behind a firewall/proxy. Under firewall settings, use the first option: I don't use SOCKS. You will then be able to send and recieve files over ICQ.
 
OK, I've got ICQ installed for her. No matter how I have it configured, it has no problem detecting the internet connection and launching on it's own.

If I go offline on my machine (the server for ICS), her ICQ will not shut down. The flower icon stays active in the system tray.

I don't really feel this is a big problem, it would be nice however, to have it behave as it should.

Any suggestions?
