Port mapping problem & outside access from my servers

jocamare — Sun, 10 Mar 2013 17:30:47 GMT

Kinda confused here.

Are the devices placed one behind the other? It doesn't look like it, but i need to know.

Then, why are both units doing a nat translation to the same IP address [172.16.30.1] when is the ASA the one that holds that IP?

Can you please explain how the traffic is supposed to flow and work across the units?

This is a very simple situation, but as always, clarification is necessary.

Final thing, i don't see any VPN configuration on any of the units, could you please elaborate on that too?

Dont be confuse...

1.i want to access to exchange Server from outside means https://my public ip /owa

2.port translated to Router to Firewall to my exchange server...Router will get public ip so i translated to ASA ..ASA translated to my exchange server (10.0.0.100)

3.I didn't configure at the moment .because of port forwarding not done properly ...i want to know in these port will use in VPN's

ip nat inside source static tcp 172.16.30.1 10000 interface Dialer0 10000

ip nat inside source static udp 172.16.30.1 4500 interface Dialer0 4500

ip nat inside source static udp 172.16.30.1 500 interface Dialer0 500

ip nat inside source static tcp 172.16.30.1 1723 interface Dialer0 1723

ip nat inside source static udp 172.16.30.1 1723 interface Dialer0 1723

ip nat inside source static udp 172.16.30.1 50 interface Dialer0 50

ip nat inside source static tcp 172.16.30.1 50 interface Dialer0 50

Router ip :172.16.30.254

ASA outside:172.16.30.1

ASA Inside:10.0.0.138

In my Scenario is I want to access my server with my public ip.i done port mapping but it could't work my exchange server and web application server. but internet is working perfectly.

could you pls advise??

What you need is something called "Nat on a stick"
