Hello...I have a Slackware based machine doing routing & QoS for my internal LAN users... It has two interfaces: eth1(100mbps) that connects to the aDSL modem(USR 9105) and eth0(100mbps) that connects to my local LAN... I''am using shorewall as a firewall...i think it''s configured well as it''s working as i want and i pass all the online firewall tests... :D All lan

Hello lartc maintainers and users! I have a router with two NICs. One NIC is connected to the Internet and the other to my internal LAN. I made a script for priorizing interactive traffic. The script matches TOS Minimize-Delay for priorizing interactive trafic, and fwmark for metropolitan packets. I have two root classes (simulating two circuits) : 1:1 for internet and 1:3 for metropolitan.

I copied and tried to adapt to my necessities the excellent script of Pedro Larroy, but I am inexperienced in QoS and I have doubts. I have cablemodem to Internet 1024kbit down and 256kbit up, through eth0. The LAN has eth1 and NAT. I formed the band so that shaping goes by the eth1 (of the LAN) with bandwidth maximum CEIL=768. But I observe that the traffic sometimes accelerates and other

Hi Here is a short description of my network: ppp0 (adsl) ppp1 (adsl) | | | | --------------------- | Router | | Firewall | | MASQUERAD | | DNAT | | | | eth0 | --------------------- | | | ---------------------- |

Hi, I have a router/firewall running Linux (like the most of you) and I wanted to do some traffic control. I''ve created an root PRIO qdisc like the example in paragraph 9.5.3.1 (http://www.lartc.org/howto/lartc.qdisc.classful.html#AEN903) with three SFQ child-classes. I wanted for interactive (ssh, telnet, ftp-control) and dns-traffic to be placed in the first queue, http should go in

Hi.... Help me please!!! I am using Linux Redhat as router of the my network. I am to making NAT and firewall. In my iptables script, I need make 3 MARKs for the same packet, as following # It marks the packets that will go for link ADSL (I have 2 links - adsl 2Mb and ''dedicate link'' 256Mb ) # I am using ''ip rule / ip route'' to make this iptables

Folks, I''m so surprised what happened to my box just in the few weeks lately. Here is my setup: INTERNET <----------> [eth0] SHAPER-BOX [eth1] <----------> USER-FARM both eth0 & eth1 got public ips (202.x.x.x) Why traffic monitored at eth0 is bigger than eth1 ? eth1 shaped just exactly the same as rate i defined in HTB. I just have 1024Kbps from my ISP and i defined the

Is there a way to add a rule to the nat table (CentOS 5.7) that would alter the port number of tcp packets destined for the server itself? I have ip_forwarding enabled, but the packets don't seem to hit the prerouting chain. I have the following redirect rule in the prerouting table. I also tried DNAT, but if the packets don't hit PREROUTING, it won't work either. iptables -t nat

Hi, I''m having issues with policing my incoming traffic by matching packet marks made by iptables. I''ve checked as many sites and guides as I can find, and I seem to be doing the exact same thing as they all are, but there''s still no success. As such, I was wondering if anyone can have a quick look to see if I''ve done anything obviously stupid? Essentially, I

Dear All, I’m working with Fedora Core 3, kernel 2.9.1, MPLS-for-Linux-4.193, and having some problems when create a HTB queue. ALL packets goes to the default queue, they don’t care about any mark or ip field I use to enqueue them. : -/ That’s the deal, all packets that incoming the interface eth2 are classified and have theirs TOS field changed following some qos policy at the PREROUTING

Hi, I use for a customer a Linux router/firewall with 1 internal interface connected to the LAN and 3 external interfaces connected to 3 different ISP. I use a kernel 2.6.17 with a routes patch from Julian Anastasov. I mark outgoing FTP traffic for the routing. With the rules below I do not have a problem with the active/normal FTP to connect on FTP server. But the passive FTP does not pass
