Two Nic's |
|
|
I have 2 nicsina server one nic goes to the router with hte network address
192.168.1.2 Default gateway 192.168.1.1 The 2nd nic goes to a switch with
the address 10.1.0.12 DG= 10.1.0.215 which is another server running dhcp,
wins, etc.
The comany is using thi sto prevent interne attacks or so they think! What
the problem is I continually get warning in the system logs saying e100b the
link is down and this is the card connecting to the internet, which is the
reason that their remote users are being kicked out of Terminal services.
When I go into the TCPIP properties I get the following warnings: Multiple
default gateways are intended to provide redundancy to a single network such
as an intranet or the internet, so on and so on!
I think because of the warning they are getting they are causing the
link to the interent t ogo down nad then they need to re start their router
so remote users can re-connect. What do you think?
Thanks for any imput!

Hi,
In most cases you should have only one default gateway set on Windows
computers with more then one NIC. If your 192.168.1.2 NIC is your link to
the internet then you should remove 10.1.0.215 default gateway on the other
NIC and only set appropriate static routes on the server.
E.g. you will probably need to add the following route on the server
route add -p 10.1.0.0 mask 255.255.0.0 10.1.0.215
Note: I am guessing what you are using for your subnet mask. If you are
using something other then 255.255.0.0 then you should replace 255.255.0.0
with what you are using...

Your right, routing between the internet router an your internal is doing
nothing. Sell them on getting a firewall. Remove the DG on the internal NIC
and add the route like Miha suggested.
