ASA 5510 firewall (ASA version 9.1(7), ASDM version 7.1) configuration to allow all inside IP addresses to access the Intranet web servers

[muhammadijaved]

Accidentally, I have to implement Intranet and Internet configurations on an unmaintained ASA 5510 firewall (ASA version 9.1(7), ASDM version 7.1).

inside 192.168.0.1 255.255.255.0
outside 192.168.1.10 255.255.255.0
intranet 102.13.112.119 255.255.255.0

The intranet (102.13.112.118) has web servers https://10.108.108.1, https://10.108.108.2, https://10.108.108.3, https://10.108.108.8:port

I need the basic configurations to implement the following two objectives:
- to allow all inside IP addresses to access the web servers on intranet
- to allow all inside IP addresses from the 192.168.0.0 network to access the outside (internet)

*The intranet must not accessible on outside (internet)

Any help would be very much appreciated…

With the following configurations all inside hosts has Internet access but Intranet configs still needed.

Intranet access done and now all the servers are accessible from inside interface after adding following nat settings

object network Intranet
subnet 10.108.108.0 255.255.255.248

object network Intranet

  nat (any,Intranet) dynamic interface

access-group Intranet_access_in in interface Intranet

Thanks all
