Cisco ASA5550 Basic Setup for testing
Greetings,
I am attempting to configure a new (to us) Cisco ASA5550 Firewall to replace one of our old Enterasys Firewalls. Right now I'm simply setting up a simple lab test where I assign an inbound port GigabitEthernet 0/0 to be an outside interface to the ISP. It has a default static route to the ISP gateway and I've setup the basic DNS information for the interface. My management interface MGMT 0/0 is using the out of the box 192.168.1.1 with DHCP. My test interface (called VCAccess) is GigabitEthernet 1/0 and is set to a 10.2.99.1 address.
Presently I am able (using the ASDM GUI) to ping from the outside interface to the gateway and to public addresses like 4.2.2.2 or 8.8.8.8. My next step was to assign a static 10.2.99.X (in this case 10.2.99.10) address to a pc and connect via the inside interface. That works, shows physical link and I can ping the assigned address from the Firewall and the Firewall from the device on 10.2.99.1. However, at this point I cannot access any outside addresses or the internet from a 10.2.99.0 network connected device. I understand that inbound traffic will require specific ACL's and NAT's but I thought that outbound (especially from a higher security [50] network to a lower security [0] network) traffic would/should be permitted.
Could someone please provide the proper basic setup for this configuration? Basically, firewall out of the box 1 Inside port, 1 Outside port, 1 management port where inside devices can access the internet. I've somehow managed to make this much harder than it should be, I'm sure.
Here's the current running config:
