Привет всем! Помогите пожалуйста. Есть два офиса, в каждом своя подсетка, территориально находятся не очень далеко метров 500, между ними протянута оптика, в одном из офисов cisco 1841 в другом 2811. Так вот скорость между ними не превышает 8 м/бит. Мучаюсь с этим уже долго... никак не могу понять в чем дело. Вот привожу конфу с 1841:
