Simple routing configuration
Hi, I have a simple question (well, at least I think it''s simple!). I have a router, with four Ethernet cards; eth0-eth3. eth0 and eth3 are the ''external'' cards, connecting to my ISPs. eth1 and eth2 are connected to my internal networks. What I want to do is basically filter all the traffic from one card to another, in this configuration: eth1 to eth3 eth2 to eth0

snooping - the crux of the problem
I have a computer with two interfaces, say with addresses 192.168.1.1 and 192.168.1.2. I want to set up routing such that when I ping 192.168.1.1 it goes out through 192.168.1.2 and not to the local interface. Is this possible - all my attempts so far have been unsuccessful? If so, pointers, etc. would be gratefully appreciated. Jim -- Jim Redman (505) 662 5156 x85

question re ip rules logic
Hello everyone, Please excuse these basic questions but I am new to Linux and I am getting desperate for answers. We are running redhat linux and after many hours of investigation I am unable to get a certain ip rule and ip route command combination to work. These are the software versions installed.

Public Router using Private Links
I am running a public core router using private links from my provider. Details: RH7.3 9 interfaces (all Intel) eth0 is default gateway and has a private IP address all other interfaces are links to other routers or networks eth3 has a public IP address The core router will rarely need to access sites out on the internet, but when it does it cannot get there because the eth0 has a private IP

Routing problem (RTNETLINK answers: Invalid argument) on multiple internet link.
Hi all, I''m trying to set up a computer with 2 routes to the internet, much as described at http://lartc.org/howto/lartc.rpdb.multiple-links.html .One of my interfaces (eth5, 192.168.2.2) is only used for traffic originating inside the network. The other (eth1, 192.168.1.2) is only used for a VPN, where all (udp) traffic originates from outside our network. I have created a second

NETWORK ROUTES
Hi all, I have a debian server with 4 network cards: The first card is used to connect to public network and this network connects with a big router. The Second, third and fourth cards are used by other networks. The first card used a dinamic route with the big router. The other cards used a static route with a little router. All runs good but my problem is when I try to use the IP of my first

Rout looping through local host.
After many many hours of frustration and failures I''m almost to the point that I don''t think this is even currently possible with Linux. With out going in to too much detail, I am effectively wanting to do the following. I want to be able to take traffic in from a local LAN on eth0 and route it out eth1 to a default gateway with a static IP. I want said default gateway

dev IFB, few questions
I''ve made some tests... eth2 is my internal interface, LAN is connected here. Before I had IMQ device in AB mode... PREROUTING [A]fter NAT, POSTROUTING [B]efore NAT. I want the same situation on ifb. I do this in this way: --- # incoming traffic here from LAN is before NAT tc qdisc add dev eth2 handle ffff: ingress # outcoming traffic here from WAN is after NAT tc qdisc add dev eth2

tables and default
I already setup several 2 gateways boxes, with rules too decide which lan should use which gateway. Now I''m stuck with a simpler problem. At home I was just making some experimental setup: * 1 adsl (ppp0) * 1 more tables in rt_tables (200 ping) called "bluff" * table ''bluff *has not* a default route root@fw-eden root # ip ro li table bluff

Network configuration
Hi, Apologies for the cross-posting; I''m not sure whether this is a firewall or routing issue, or both! I have four network cards, detailed below. eth0 and eth3 connect to my ISPs, and eth1 and eth2 connect to local networks. I want to route all traffic from eth2 to eth0, and from eth1 to eth3. However, I am having a few problems with this. eth0 ip: 192.168.100.253/24 gw:

one dude about rt_tables
Can I add routes to rt_tables by hand with the vi editor? If I add a route to that file, it will be there if I reboot the box? I am sure there are stupid questions but I can''t find the answer into the papers I have here. Luis Miguel Cruz Miranda.

policy routing at its best
hello list (and martin) ;x i have now composed my final(?) policy routing design. the goals i had when beginning with this, for you that have not follow mine and martins thread, was to 1) only let 192.168.1/24 to see all routes, 2) not route between defined networks, except to and from 192.168.1/24 and 3) not defined networks should only be able to reach 192.168.1/24. this might sound simple.

Multiple Internet facing Nics - Gateway issue
I have a server with 4 nics. Two are using different internet connections, both with static IP's, and two are connected to our private network. The two internet facing nics seem to be battling over the gateway designation. Which ever I designate as the gateway the other stops responding to incoming traffic. I need both to listen to inbound traffic. One for our main web page and the other
