Currently I have a number of clients within our network who have their own VLAN's. We have allocated them Public IP addresses on our firewall which NAT through to their VLAN's. When outside of our network they can connect to these public IP addresses on port 80, 21 etc depending on the services the have running. however when they are inside our network they cannot connect to these public IP addresses at all.<br />
<br />
Is it possible to configure this and where do I do it. I am currently running an ASA5520 firewall with ASA version 7.2(1)

Can I set our ASA5520 to allow a user from within the LAN to connect to an external IP address which is on the WAN interface of our Firewall?

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
