Been running this for quite a while and noticed that have intermittent problems getting out. Find that if I ping the same site from 2 computers it may work on one and fail on the other. Also was surprised that some time they are going out different interfaces at the same time. Seems to work all the time from the firewall.

...d some manuals and I guess I should use the same address with a different netmask in WAP(eth0) and put a route in the Linux box and use a fake arp entry in the eth0 interface of the router. I''d appreciate any hint you can give me.

Hi, I have three linux machines, and I want to let one of them forward packets betwen the other two. The forwarding node has two ethernet cards, connecting the two two machines respectively. However, when I ping between the two end points, the forwarding node can receive the ping requests at its eth0, but it never forwards them to its eth1. So is the reverse direction. The forwarding node is

Hi, I thought sending email went out on port 25? When I look with ethereal, outbound email transfers were on port 58020. I assume it''s choosing a random port for transfer? If so how do I tag it with iptables mark? I was hoping it was as simple as tagging port 25. Thanks, Mark

Hi. Has anybody experienced problems with HTB and latency? The case is: I''m allocating traffic for HTTP traffic. It seems more responsive without using HTB.

Hi all!! I was trying to figure out how iptables marks work. I thought that a packet could just be marked once into a chain (if the packet matchs the criteria, then it the action is applied, and that''s all for the packet into this chain), but I was wrong: I did iptables -t mangle -A INPUT -i eth0 -j MARK --set-mark 7 iptables -t mangle -A INPUT -i eth0 -j MARK --set-mark 8 and then

...s that there is one occurrence of "A B" repeated 4 times in the original table, and it is summarized in the second table, computing the sum of the weights. I solved the problem using Perl, but I'd like to know what I have to read in order to do it in R. Regards, Nelson.- -- http://arhuaco.org

I have two ISP connections, and am having some issues. I can connect to any services on the firewall, like the smtp gateway, but anything on the internal server only works from one connection. The lartc guide has a good example for what to do for services on the box, but leaves it open for how to handle services on an internal host. I''ve tried using iptables to mark the packets

Hi. I am trying to shape my upstream bandwidth, mostly per port. and I am having some problems getting things to work the way I want them to. before I throw my configuration at you guys ;), I`d like to debug it by myself - but I was not able to find a tool that allow me to monitor current bandwidth usage per port (and preferably even per port+ip). I want to know what is the current bandwidth

Hi! I''m doing load balancing for 5 dsl lines, each one with a dsl router attached to a linux machine ethernet plug. The problem is that I''m adding 15 more dsl lines, and I don''t have enough PCI slots in the linux machine to sum up 20 ethernet plugs (I already have 2 quad ethernet cards). So I''m considering connecting all dsl routers and the linux machine to a
