[UFW BLOCK]

[indigo9]

Господа, приветствую!
Нужна помощь знающих iptables, т.к. пока новичок. Заранее благодарен!
Есть сервер (winsrv2008, ip:10.0.88.184), на нём есть расшаренная папка для всех юзеров. В этой же папке есть приложение, которое запускают юзеры. Данная программа работает по протоколу UDP, порт 12726. У юзеров из подсети 10.0.88.176/28 данная программа работает без проблем, а юзерам из подсети 10.0.33.0/24 блокирует Ubuntu-шлюз. Топология во вложении.
