[mcmilad]

سلام
من یه مشکل عجیب با FTP دارم تو آیزا
یه رول دارم به این صورت:
از: internal
به: External
all outbound traffic
all users
ولی هیچ ftp باز نمیشه دو جور خطا میده یکی:
Error Code 10054: The server you are attempting to access ended its connection with the gateway
یکی دیگه:
Error Code: 502 Proxy Error. The login request was denied. The logon account might have been disabled or logon information might have changed. Log on again to verify that the information was typed correctly. If the problem continues, report the problem to the administrator of the Internet server you are requesting. (12015)
