I have an Ooma VoIP device on my home network. I do not want it to act as the router to the internet as I already have a dual-nic linux box that is working just fine. I do want to start using a priority qdisc to make all traffic from the ooma device as high priority, torrents as low priority, and everything else as normal priority. I've tried a variety of settings and I must not be doing it quite right as everything I try dumps nearly all packets in the middle priority class. On my linux box (CentOS 6) eth1 is the internal network and eth0 goes to the internet.
Thanks!

I have 2 computers with debian installed on both. One computer has no sceen or othe prepherels accept ethernet port. I've connected them through a lan cable and shared the intenet to be used by the computer that has no sceen. However, I'd like to ssh this computet but I don't know its ip address. BtW, I dont have a router.
Use Angry IP Scanner. It will give you the list of devices in the network.

I am using RHEL 6.3 (2.6.x kernel). I have tcp based client server applications. I noticed that when i run them on the same host, the throughput is approx the same, irrespective whether server binds to loopback or local IP assigned to NIC.
What is the reason behind it? My understanding is that loopback is software based routing, where as when local IP assigned to NIC is involved, the hardware is involved in the data path. Is that true?
The hardware does not get involved.
As soon as the routing function knows that the destination address is local, the packet is switched to ingress path. Which is incidentally why sniffers can't capture such packets, because that hook happens to be after the point of this decision.

I am running linux machine between two IP Phone with Two NIC card's. all of the traffic passthroug between eth0 and eth1 should move through TCP/IP stack.currently,IP-forwarding is enabled in linux and traffic route directly at Kernel level. If I am doing port forwarding using IPtables, I can get the traffic in TCP/IP stack but I dont want to perform port forwarding. Every time traffic is having different port, its difficult to map the port again with its original port.
Is there any other mechanism, I can get every packet in tcp/IP stack without port forwarding either using some routing or creating virtual interface/loopback interface?

I am looking for help on getting IPv6 to my Xen domU's. I currently have one 6in4 tunnel from HE for each guest and would like to consolidate that to one on the dom0. But I am not set on that-- I am completely open to suggestions.
Based on my research both here and on Google, I am not finding anything great. For what it is worth, the dom0 is running Centos 5.8 and Xen 3.0.
Sounds good to me. Set up radvd on the dom0 to advise the routable /64 they give you and have the domUs get an address from it.

Can somebody tell me what are the ways of routing packets in a linux system. I have an external and internal network interfaces on my linux system. I want to forward packets arriving at my external network to an internal network.
I do not have iptables. What are the other ways to this? What commands are offered by native linux. Should Netfilter always be enabled for this? My kernel does not come with Netfilter.
So please suggest.
Thanks in advance
Assuming you're talking about real routing, and not any form of Network Address Translation (NAT), you just need to enable IP forwarding, and put the relevant routes in your routing table:
echo 1 > /proc/sys/net/ipv4/ip_forward
Configuring NAT does require iptables.
