port forwarding in isa

سلام خدمت اساتید عزیز
من میخواستم پورت فورواردینگ روی isa راه اندازی کنم تا یه جاهایی هم انجام دادم ولی نمیدونم درسته یا نه

یه مودم Adsl دارم با رنج شبکه 192.168.1.0
و شبکه داخلی با رنج 192.168.30.0

isa server : internal 192.168.0.2
isa sertver External : 192.168.1.2
حسابداری :192.168.0.1
میخوام نرم افزار حسابداریه از طریق ip static قابل رویت باشه که Ip هم از شرکتی که Adsl رو گرفتم گرفتم
پورت نرم افزار تحت وب رو به :81 عوض کردم و تنظیمات port forwarding رو روی مودم انجام دادم (192.168.0.1:81)
نمیدونم درسته یا نه آیا باید به isa فوروارد کنم یا خوده سروره حسابداری ؟؟؟؟؟؟
یه سری تنظیمات publishing رو هم انجام دادم
