This is MUCH easier than it sounds once you have seen it done. Multiple nics on the same subnet are a recipe for trouble, unless you're using NIC Teaming.Also, I think using the loopback DNS address instead of the real DNS also throws dead By creating an account, you're agreeing to our Terms of Use, Privacy Policy and to receive emails from Spiceworks.

You can manipulate the routing table with the 'route' command. I see you tried a VLAN subnet, did you change the port settings on your switch to put this PC on that subnet, that could be part of the reason it Machines connected to eth1 will not be able to see the Internet unless you have some type of NAT masquerading enabled.

In IPv6, I think it's even standardized how to specify the interface to use: you could connect to e.g. The situation is that you've got two, or more network cards.

Some days it just doesn't pay to wake up in the morning! have a peek at these guys Although there are a LOT of routing and rules one can apply, all we care about at this point is to make sure that packets that come in on a given I'm still reading up on metrics and teaming, but my question is, why can't I ping Your ifconfig and route output looks OK to me, but then I've not used a rh based distro since '99...

The ifmetric package The ifmetric package enables us to manipulate metrics of routes a posteriori even for DHCP. Can I use that to take out what he owes me? I installed Centos 5.6 with 2 nics, set them up on 2 different networks, made the routes etc, but only one works (reaches out)... check over here I suspect this is slowing my network way down too.The specs are:Windows 2003 ServerLAN 1 IP: Sub: GW: DNS: 2 IP: Sub: GW: DNS:

It sounds like you are missing a route for from the 10.30.0/24 subnet. share|improve this answer answered Jul 30 '13 at 8:18 Ronin Tom 1443 The OP only has one default route, through over wlan0 (as desired). is reachable over One of them is a gateway to a client's internal network, and I have a static route set up to forward traffic for that network over the VPN.

I'm lost.

If the firewall was on, the traffic count on NIC 2 would not increase from the external pings. –Chris Welch Oct 3 '14 at 15:35 1 Tore down the interface Not the answer you're looking for?

Either way, good luck and have fun.Click to expand... This is useful for testing interfaces individually without having to worry about conflicts. Edit: to simplify: I'd be just fine not using eth0 at all ever again, I just need wlan0 to function and accept incoming pings and SSH connections, something that ATM it's this content Any idea why this is happening?

That said, please have a look at my comment to the question itself. –Michael Kjörling Jul 30 '13 at 18:54 Any way to use UFW for this? What now? In resolv.conf I've only got the DNS servers IP and domain clause. Drawing picture with TikZ How do fonts work in LaTeX?

Use whatever editor you prefer although I prefer "nano" and so will use that for this walk-through, Code: nano /etc/sysconfig/network-scripts/ifcfg-eth0 creates the first configuration script and its contents are : Code: Now, before you start configuring other interfaces, we will configure the routing and rules for that routing for the first NIC. Even worse, if the interface is using DHCP, it won't be pingable by the DHCP server, and other bad things can happen.The full answer, I believe is:1) assign these two interfaces TECHNOLOGY IN THIS DISCUSSION Connection Alternative Networks Join the Community!

You may want to wait a couple of minutes before testing it because it can take some time for it to actually come up and definitely wait for a command prompt Is there any known limit for how many dice RPG players are comfortable adding up? that's the right way to do it with 2003. Setting up network routes is one issue, but it took me a long time to find out, that I have to set up ip_forwarding, too.

I don't know if you can make the delete permanent, but you can make the route adds static and persistent through reboot by using the -p flag. At the command line type: Code: ip rule add from [IP ADDRESS]/32 table [TABLE NAME] The "/32" restricts the rule to just that address.

As mentioned, we will be issuing the commands to perform the configuration manually, to test them and then, committing them to a script after testing. (X) indicates the number of the I find that a bit strange since that's a public subnet. Do you need this, can you remove? To specify a rule for packets coming from the interface, we execute Code: ip rule add to [IP ADDRESS] table [TABLE NAME] .
