I''m having trouble routing on high fwmarks, I want to use a lot of different marks for 2 routes so that I can QoS based on the marks ip rule looks like this: 0: from all lookup local 32751: from all fwmark 31 lookup dslout 32752: from all fwmark 30 lookup dslout 32753: from all fwmark 29 lookup dslout 32754: fr...

hi I have trying to remove the extra rules from my routing tables, however with no luck Also I want to know these duplicate entries have an effect on packets going routed? I have this overwhelming rules lists from my predessor who added the "ip rule add fwmark" entries in firewall script, and on each run of firewall script its creates an extra entry in routing table. Now what I want to get rid of an extras "from all fwmark 0x2 lookup squid.out" leaving only one that what''s I needs. here is the output of "ip rule ls" 0...

...ce I tried to use this marks in the RPDB : the packets where successfully marked, but it seemed that RPDB didn''t succed in matching them (for those who already know the answer, I only used marks above 9). After googling a while, I found that ip(8) only accepts hexadecimal numbers for "fwmark" statement. IMHO, I think that allowing only hexadecimal values in ip(8) while iptables(8) allows to either use decimal or hexadecimal value is quite inconsistent. I checked ip(8) sources, and here is the point : } else if (strcmp(*argv, "fwmark") == 0) { __u...

Could someone comment on the benefits of using CLASSIFY vs fwmark (or vice versa) in iptables? I''m getting ready to implement some basic tc for VoIP and most of the examples seem to use the (older?) fwmark syntax. Should I convert these to CLASSIFY? Can the two syntaxes be mixed? Also with U32? TIA, Edwin -- <=+=+=+==+=+=+==+=+=+=+=+=+=+=+=...

Hi everybody, I''m trying to set up routing for 2 links to the internet on a box which produces traffic itself (e.g. DNS) and will route all our local traffic. AS one route is quick and expensive and the other one slow and cheap, I want to be able to route packets for some high-level protocols to the second link. If I correctly understood table 3-2 in

Hello all, I am working with kernel 2.2.20 with the necessary options configured into the kernel to support all of the wonderfully fancy routing features: - routing based on ToS - routing based on fwmark - multiple routing tables This same kernel is in use elsewhere, and is routing based on fwmark with success. This leads me to believe that my kernel is OK and that I have another problem. problem description - - - - - - - - - - I have marked packets using ipchains, created another routing...

Hi all, I need to route local generated packages depending on which tcp or udp service I need to use. To accomplish this I have configured two routing tables: [root at lothlorien ~]# ip ru ls 0: from all lookup 255 32762: from all fwmark 0x2 lookup FirstLan 32763: from all fwmark 0x1 lookup SecondLan 32764: from 172.25.80.10 lookup SecondLan 32765: from 172.25.70.18 lookup FirstLan 32766: from all lookup main 32767: from all lookup default My routing tables: [root at lothlorien net]# ip ro show table FirstLan 172.25.70.16/28...

...iptables, matching packets based on IP address and marking them with an ID. Multiple IP addresses can be marked with the same ID. We then filter based on the ID. We have close to 2000 filters now and I''m looking into hashing tables. Is there any way to create a hashing filter based on the fwmark? Paul C.
