Port Forwarding với ASA 5505

[chairuou]

Hi all,

Tôi có network như sau

LAN ---> Cisco ASA 5505 ---> Internet

giờ có 1 web server trong LAN, muốn map port 80 từ ASA vào LAN nhưng không được. Cấu hình hiện tại như sau:

Nhờ mọi người check giúp xem sai gì mà không access được Web server? Sai cấu hình NAT ?
Xin cám ơn !

bạn bỏ thử 2 câu lệnh http command trong cấu hình ASA bằng cách:
no http server enable
no http 192.168.0.0 255.255.255.0 inside
http 0.0.0.0 0.0.0.0 outside

bạn nên sử dụng port khác ngoài port 80 của ASA để tránh rắc rối ví dụ như mapping sang port 8080
