FTP Err Msg: Error: Connection Timed OutLast reviewed: November 10, 1997Article ID: Q169268 |
The information in this article applies to:
SYMPTOMSWhen you try to connect to a site via FTP, you may get the following error message after a few minutes if the Internet Information Server (IIS) is configured with more than one default gateway:
Error: Connection timed outThis may also happen only when you try to connect via FTP using a slow link (for example, a 28.8k modem connection) to a server that has more than one default gateway.
CAUSEThe IIS computer should have only one IP default gateway. The IP address of the default gateway should be configured on the external network adapter card only. This requirement is a result of the basic architecture of TCP/IP. Only one default gateway must be defined on a host that resides on two or more non-connected networks. If IIS server is configured with more than one network interface, it is connected to two networks that are by design non-connected. A default gateway is a router that is supposed to be used for all traffic that has no specific route. If you have two default-gateways, the IIS server TCP/IP stack will assume that they lead to the same set of networks. This will cause the IIS server to send Internet traffic to the internal network, or internal traffic to the Internet.
WORKAROUNDRemove the default gateway from the advanced TCP/IP settings of the internal network interface on the IIS server and define static routes to the internal network segments. For additional information, please see the following Microsoft Knowledge Base article:
ARTICLE-ID: Q161380 TITLE : Only One Default Gateway Allowed On Proxy ServerBecause no default gateway will be defined for the internal network, you must add static routes using the Route Add command. These routes can be made persistent by using the -p command switch.
