Hello everybody,
i have to replace our zywall with an 5520 asa.
the following configuration:
outside-ip: 82.218.6.10/255.255.255.255
default route 82.218.6.254
inside-ip: 10.0.1.201/255.255.0.0 dhcp 10.0.5.1-10.0.5.100
wlan-ip: 192.168.0.1/255.255.255.0 dhcp 192.168.0.2-100
dmz: 82.218.135.6/255.255.255.248
our mailserver(dmz-network) 82.218.135.3 is connected to the dmz.
an rdp-server(inside-network) 10.0.1.200:3389 should be reached from 82.218.6.10:3389
connections from inside out outside, inside to dmz and inside to wlan.
connections from wlan to outside, wlan to dmz
connections from dmz to outside
should be possible.
connection from outside to dmz only for port 25,110,143,80,443,22 on ip 82.218.135.3
connections from outside 82.218.6.10:3389 to ip 10.1.0.200:3389
i have problems to implement the connection to dmz and rdp-server
can anyone help me ?
mike
