У меня есть 2 ПК, соединенных коммутатором.
PC1 - <-> - Switch - <-> - PC2

Оба компьютера имеют Windows 7.
Оба могут подключаться и обмениваться файлами друг с другом.
Оба компьютера могут подключаться через удаленный рабочий стол.
Брандмауэр отключен на обоих компьютерах.
Но я не могу подключиться с ПК1 к веб-серверу на ПК2 через порт 80.
ПК2 имеет прокси-сервер, работающий на порту 8888.
Я могу подключиться к порту 8888 через разъемы от ПК1, но не могу подключиться к порту 80. Тайм-ауты подключения ...

В чем может быть проблема и как ее можно решить?
