сделал я его, закачал ему прошивку старую wg01070506_WL500g_en.trx с помощью Firmware Restoration. Он ее схавал, перегрузился и стал говрить что он нормальный, не делюксовый. А затем ему скормил уже прошивку от Олега для простого роутера. Сейчас заработала флешка. Буду дальше его пытать
В дефолт не забудьте сбросить...
Дано. Подключение к интернету через локальную сеть посредством PPtP, ограничений по TTL вроде нет.
Странность заключается в том что если я делаю tracert с виндового компа (кабель подключён к нему напрямую) то получаю такой результат:
А если я делаю traceroute с точки (кабель в неё, я через WiFi по телнету в консоли) то получаю такой результат:Code:C:\Documents and Settings\User>tracert www.ru Tracing route to www.ru [194.87.0.50] over a maximum of 30 hops: 1 <1 ms 28 ms 30 ms vpdn-1.mipt.ru [193.125.142.226] 2 15 ms 21 ms 21 ms vpdn-gw.mipt.ru [193.125.142.97] 3 1 ms 1 ms 1 ms RT502-001.retn.net [193.232.244.187] 4 1 ms 1 ms 1 ms GW-Demos.retn.net [81.222.8.46] 5 8 ms 8 ms 3 ms iki-1-vl10.demos.net [194.87.0.83] 6 11 ms 10 ms 10 ms www.ru [194.87.0.50] Trace complete.
Если сделать tracert с Win-компьютера при подключении его через точку то добавится ещё один хоп (моя точка) и второй-третий хоп (vpdn-1 и vpdn-gw) опять будут звёздочками.Code:[root]$ traceroute www.ru traceroute to www.ru (194.87.0.50), 30 hops max, 38 byte packets 1 * * * 2 * * * 3 RT502-001.retn.net (193.232.244.187) 4.430 ms 3.562 ms 3.527 ms 4 GW-Demos.retn.net (81.222.8.46) 6.493 ms 6.361 ms 5.893 ms 5 * iki-1-vl10.demos.net (194.87.0.83) 13.045 ms 14.530 ms 6 www.ru (194.87.0.50) 8.577 ms 8.143 ms 7.491 ms
Пытался решить проблему следующим образом:
1. Изменён внутренний диапазон адресов, чтобы исключить пересечение с локалкой прова.
2. insmod ipt_ttl
insmod ipt_TTL
iptables -t mangle -I PREROUTING -i vlan1 -j TTL --ttl-inc 1
3. (правда я тут несколько не уверен в правильности команд)
iptables -A OUTPUT -s 172.16.1.126/255.255.255.255 -o vlan1 -j ACCEPT
iptables -A OUTPUT -o vlan1 -j DROP
4. была попытка задать более длительное время ожидания при traceroute с точки
5. попытка запустить traceroute с флагом -I
Позже вечером могу привести результат команд
iptables -L -vn
iptables -L -vn -t nat
iptables -L -vn -t mangle
route -n
ifconfig -a
То же самое, так и не найдено решение... http://wl500g.info/showthread.php?t=9622
такая же фигня, ток вообще ни один хоп не проходит... пинги нормально...
Посмотрел дамп, снятый с vlan1, и немало удивился, увидев в ip.src внутри туннеля IP с интерфейса vlan1. И что ещё больше поразило, ведь ответы-то от всех хопов приходят, но на верный ip.dst от ppp0. А вот если при трассировке явно указать source ip (-s), наблюдается обратная картина: первые хопы, что идут через vlan1, не отображаются, остальные внутри ppp0 видны:

этот порт добавляется, если на web страничке настроек Virtual DMZ, стоит поддержка Starcraft
но он не должен влиять ни на что, имхо...
кстати, перепрошил на пре12, и теперь у меня трейсит все корбиновские точки, а уже выход в инет нету...
