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

Hi, I have emailed the list before (email can be found here http://mailman.ds9a.nl/pipermail/lartc/2005q4/017220.html) regarding this matter. Basically, I am trying to set up a router for my college, to route conference guests over an adsl line, and students over an academic connection. I''ve looked at man ip(8), and a few examples, and think I have a configuration that will work, but was

Hi, I have a linux router with 4 ethernet cards; eth0 through eth3. Basically, all I want to do is route all traffic from eth2 to eth0, and all traffic from eth1 to eth3. I''ve looked through the LARTC how-to, specifically at chapter 4, about multiple providers. However, I am still a bit confused, and not sure how to set up my routing tables, as my scenario differs from the one in the

Hi, I am trying to set up a linux box to act as a router for my college. There are two different types of users; students and conference guests, and they have IPs statically assigned by DHCP, from separate ranges (but they are on the same subnet). The students go out onto an academic connection (via eth0), and conference guests go out on an ADSL line (via eth3). eth1 and eth2 are configured for

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

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

Dear all, If I do cause offence by posting OT here I apologise in advance, I am however desperate for help and after posting on other forums without any ideas I know many networking experts will see this here and hope they can enlighten me.

Hello. I have the problem that I have two gateways on the same subnet, 80.237.244.1 and 80.237.244.33. Both gateways are 100 MBit cards, so I have 2 times 100 MBit to the Internet. The NIC in the server is a gigabit-card, so this card is easy able to use both gateways for outgoing traffic. Now I just want to use both gateways for my outgoing traffic but no matter what I do, it doesnt work. I

Hi all, i''m puzzled by a ploblem and I don''t know how to debug it... I have a firewall with 2 gateways, adsl and isdn. Main gateway is via adsl, backup via isdn. I setup 2 table ''adsl'' and ''isdn''. You can find a description below. I made a script to test both tables. That mainly 1. adds an iptables -t mangle -A

It seems like tos should be considered when sorting routes on insertion. Consider this out-of-order route creation: # ip route add 1.1.0.0/24 table 3 nexthop via 192.168.0.23 # ip route add 1.1.0.1/32 table 3 nexthop via 192.168.0.24 # ip route show table 3 1.1.0.1 via 192.168.0.24 dev eth3 1.1.0.0/24 via 192.168.0.23 dev eth3 ok... it''s re-ordered the routes - it makes sense, the
