Перестает пинговаться интерфейс при обращении к Squid на нём...

Очень странная ситуация. Есть подсеть. У подсети есть маршрут по умолчаию - ip адрес 192.168.3.1. На интерфейсе поднят прозрачный прокси. Если люди работают на прямую без прокси, то всё хорошо. Если хотя бы один запрос отправляется из этой подсети на прокси, то 192.168.3.1 становится недоступным и не пингуется. Остальные адреса в подсети остаются доступными. Лечится всё просто - ifconfig eth0 down - ifocnfig eth0 up + юзеры перед этим пускаются в обход прокси.

Есть ещё одна подсеть с маршрутом по умолчаю 192.168.2.63. И в ней все ходят в инет через проксю, и проблем не наблюдается, даже когда проблемы есть в соседней подсети.

Маски подсети везде = 24 бита.

Но мне нужно, чтобы обе посдети ходили в инет через один прокси, а не только одна. Помогите пожалуйста! Конфиги фаерволла и сквида прилагаю.

покажите таблицу маршрутизации до и после "192.168.3.1 становится недоступным и не пингуется."

Так мне не понятно назначение правил:
$IPTABLES -A INPUT -i $LAN_IFACE_SMS -s 255.255.255.255 -j DROP
$IPTABLES -A INPUT -i $LAN_IFACE_SMS -d 0.0.0.0 -j DROP

И не понятно зачем нужно:
echo "1" > /proc/sys/net/ipv4/ip_dynaddr

Вот вся диагностика, которую вы спрпашивали, простите, что припозднился. Не нужные правила, смысл которых непонятен, убрал, не помогло. вывод dmesg в следующем сообщении (не влезает)

TO edigaryev:

Совет хороший по поводу подсветки, но...

"GTFO" - давайте без оскорблений, то, что вас не видно по ту сторону провода, не означает, что можно безнаказанно материться.

За _мат_ приношу извинения, но постить объемные версии логов лучше на pastebin'ах.

>Если хотя бы один запрос отправляется из этой подсети на прокси, то 192.168.3.1 становится недоступным и не пингуется.

192.168.3.1 -- если пропинговать хост до того как кто-либо пытается сделать коннект на порт прокси сервера? Ну или скажем, зайти по ssh?

Были ли раньше подобные проблемы?

Если пропинговать до того, как кто-либо попытается соединиться с прокси - всё пингуется великолепно...

Была раньше эта проблема, думал, дело в acpi, сделал acpi=off в lilo.conf, вроде бы даже это помогло на время. Но теперь опять всё падает...

меня смущают watchdog - записи в dmesg... Может, стоит копать туда?

Вот, нашел: http://www.ambience.sk/azureus-transmit-timed-out

Sometimes network connection on Linux goes down with short message in syslog saying: "[localhost kernel] NETDEV WATCHDOG: eth0: transmit timed out" (or similar).

Some network-heavy programs or the buggy driver/kernel handling of traffic could cause this error. Azureus (torrents downloading software), for example, is often guilty for this.

Solution is to offload the network card - run the following command in the console: ethtool -K сетевой_интерфейс tso off
