UDP трафик не проходит через Port Forwarding

[Ivan Semenov]

Почему то на роутере Keenetic с белым IP TCP трафик работает форвард портов, а UDP нет

 

На внешнем компьютере делаю тест TCP и UDP трафика, один проходит, другой нет

Mac % iperf3 -c 95.xx.xx.xx -p 8082

Сам пророс порта с 8082 на 8080 настроен

 

[kpdozer]

Хотя прошло много времени, но может будет кому полезно. У меня  PPPoE (Ростелеком). Помогло передернуть вот эту настройку.
