NIC Card Message

I get the following error on my web server when I try to change some of the
properties on the NIC Card:

Warning- Multiple default gateways are intended to provide redundancy to a
single network (such as an intranet or the Internet). They will not function
properly when the gateway are on two separate disjoint networks (suh as one
on your intranet and one on the Internet). Do you want to save this
configuration. What does this message mean.

Hi George,

Do you have more then one NIC card in your server? If yes, did you set
gateways on both of them?

Yes we have multiple nics. I haven't set gateways for one of them. Special
circumstances required my the server. What does this message mean.

This message means that you have set default gateway on more then one NIC.
In most cases computers should have only one gateway -- even if you have
multiple NICs.

Hello,

Thanks for posting!

I understand that when changing the properties of TCP/IP on the NIC card on
your web server, the following warning message happened:

"Warning - Multiple default gateways are intended to provide redundancy to
a single network (such as an intranet or the Internet). They will not
function properly when the gateways are on two seperate, disjoint networks
(such as one on your intranet and one on the Internet). Do you want to
save this configuration?"

If I have misunderstood your concerns, please feel free to let me know.

From your warning message, I suspect that the web server could host
multiple NIC cards. However, they are having their own gateway on separate
networks. Based on my research, only one default gateway should be
configured on any multihomed computer. The default gateway is a global
configuration for the server, not a setting that must be set for each
network adapter. The server is already aware of all the networks it is
directly connected to, and adds a route to each network for which it has a
TCP/IP address.

Hope the information helps.
