John, Well now that the list is back up, here's the e-mail I sent to you that bounced Jim Dettman President, Online Computer Services of WNY, Inc. (315) 699-3443 jimdettman at earthlink.net Hi John, <<The problem is that their network and mine were both using 192.168.0.xxx. The network guy that set everything up for the client asked me to change my system to 192.168.1.xxx which I did. Everything came to a crashing halt on my system, at least in terms of getting to the internet. In fact weird things would happen like... some chat clients worked (yahoo and aol), others didn't (msn).>> Yeah, that would put the breaks on everything and something you probably didn't need to do. <<However this now means that I have to manually configure all of my computers since when they obtain automatically, they end up with the default gateway address of 192.168.0.1 which doesn't work. This is going to cause problems when I hook up my tivo box which I can't get at the settings to set manually.>> First, I'd go back to the way everything was, as you didn't need to change it in the first place. <<So... the question is, where the hell is this Default Gateway setting configured. It seems like it should be part of the router configuration but I simply cannot find that setting in the router's setup stuff anywhere. >> There are two ways to setup a network: with a DHCP server and without. Without one you need to manually specify the IP address, the gateway, and the DNS servers in Windows. With a DHCP server, you don't do any of that manually. The PC at startup broadcasts a DHCP request and the DHCP server (in this case your router) supplies all that info. In Windows, the only thing you need to do is to set it for "Obtain IP address automatically". In your router setup, the router is has two addresses that can be assigned: the internal network and WAN port. The WAN port IP is your external address (used to talk to the rest of the world) and something which your ISP either sets dynamically or is static. The internal address is the one you want to change and the one that is supplied to the DHCP client as the Gateway Address. So your not looking for "Gateway" but "internal IP address" or "Network IP". This is a fundamental setting for the router. When you change it, you'll loose communication with the router until you reboot your PC. As to what I mentioned earlier, you didn't need to change all this because the address on the remote end at the client is not the one you need to be using. The address you gave is for private networks only and not a public one. Your client has a router/firewall in place and NAT (network address translation) is being used, same as in your router. The 192.168.0.x is a private address and neither of you will be able to find each other on the Internet using that address. The addresses you need to be working with are the WAN addresses set in your routers. If neither of you have static addresses with your ISP, then you'll need to get them or use a 3rd party such as www.dyndns.org to establish communications. Fill me in with what your trying to do and I'll help further if I can, but for now, set things back to the way they were. -----Original Message----- From: AccessD-owner at databaseadvisors.com [mailto:AccessD-owner at databaseadvisors.com]On Behalf Of John W. Colby Sent: Friday, January 24, 2003 11:11 AM To: AccessD Subject: [AccessD] OT: network help Guys, I am having network troubles at my home office. Here's the situation. I have a small network running on a dlink DL-704 router. WWW connection through my cable, thus a cable modem. The router is the dhcp server. Internal addresses were 192.168.0.x with the router being 192.168.0.1. Understand I am not a network guy so I can spout this stuff but you should not mistakenly conclude that I understand it. The problems started when I tried to set up a Remote Access connection to a client system. I could get the virtual channel to run but couldn't get to the "server" on that system which was set (internally to THEIR network) to 192.168.0.10. The problem is that their network and mine were both using 192.168.0.xxx. The network guy that set everything up for the client asked me to change my system to 192.168.1.xxx which I did. Everything came to a crashing halt on my system, at least in terms of getting to the internet. In fact weird things would happen like... some chat clients worked (yahoo and aol), others didn't (msn). On closer investigation it seems that the default gateway is still set to 192.168.0.1. Since everything else is set to 192.168.1.xxx (including the router - 192.168.1.1) it appears that this default gateway number is causing havoc. We could not find where this number is assigned, IOW how to change it (default gateway) from 192.168.0.1 to 192.168.1.1. The "answer" was to go set the TCP/IP properties manually to "use the following address" instead of "Obtain an IP address automatically". Once I go in there and set the info manually, including the "default gateway", everything works. However this now means that I have to manually configure all of my computers since when they obtain automatically, they end up with the default gateway address of 192.168.0.1 which doesn't work. This is going to cause problems when I hook up my tivo box which I can't get at the settings to set manually. So... the question is, where the hell is this Default Gateway setting configured. It seems like it should be part of the router configuration but I simply cannot find that setting in the router's setup stuff anywhere. If anyone can help me with this, it would be much appreciated.
