Hello I working on finding out a strange networking problem with one of our linux gateways between the internal LAN and DMZ. This machine runs: Debian6 with 2.6.32-5-amd64 kernel, have 2gb of mem from which 1 is free. It has near to 1 year uptime and has absolutely nothing changed on it. All it does is some natting and packet filtering with iptables. Network diagram: INET <> Router1 (BGP) --- DMZ --- Router2 (This One) <> LAN So about 2 months ago windows machines (WinXP-Win8) started acting strange, connections got interrupted, webpages didn't load for users. After weeks of investigation into this and going through all the components on our network I finally determined that this machine is the problem so as a workaround I installed another linux box and all the windowses using that as a default gateway right now. It is a workaround what I wouldn't like to leave in place forever. For example it was happening one morning when I plugged a new win7 laptop in and 1 of our bgp routes were disabled on a server prior to this gateway the laptop simply couldn't go out to the internet (while all the other linux machines had no problem whatsover), when I reenabled the bgp route on the first router it started working. This just doesn't make sense, the machines behind this gateway don't know anything of the outside network (DMZ) because they are natted out there. I try to make sense of all this but can't and I'm hoping some networking gurus here can give me tips what is causing this error. Here are the kernel values from the gateway (I don't think any other interface statistics like ifconfig are relevant, there are no errors:0 on the interfaces, the link is not flipflopping and as I said everything works just fine with linux clients) : kernel.sched_child_runs_first = 0 kernel.sched_min_granularity_ns = 3000000 kernel.sched_latency_ns = 15000000 kernel.sched_wakeup_granularity_ns
