Giúp mình phần cấu hình Firewall ASA này với

[Guest]

Mình cấu hình VPN client access nhưng khi vpn vào thì thấy lớp mạng bên trong nhưng vẫn không telnet được vào firewall và máy client access lại không ra được internet, còn cái phần split tunnel mình vẫn chưa hiểu rõ nữa, các bạn hướng dẫn mình với !

Chào bạn,

Để client access có thể truy cập Internet khi đang dùng VPN bạn bật thêm chức năng split tunnel trên ASA để chỉ các lớp mạng này được mã hóa, bảo mật.

Còn về telnet
telnet 10.59.25.0 255.255.255.0 Inside
ip local pool VPN_POOL 10.59.0.20-10.59.0.100 mask 255.255.255.0

Cám ơn bạn nhiều nhé ! Cái phần telnet vào Firewall khi vpn client access vào vẫn chưa được bạn ơi ! Có cần tạo thêm access-list nào ko ?

[thanhnam0707]

nếu bạn access từ outside thì phải dùng ssh, trên outside không hổ trợ telnet.

dung command nay

management-access inside
telnet a.b.c.d 255.255.255.x inside

OR/AND

ssh a.b.c.d 255.255.255.x inside

a.b.c.d la vpn client ip
VPN vao va` trelnet vao` inside ip address
