It's simple, how do I hard reset my Cisco ASA 5505. I found different procedures for restoring via CLI etc. There's nothing on how to use the RESET button in the back.

Are you trying to power cycle the unit or return it to factory default?

Power cycle ->
pull the plug

Set config to factory default -> http://www.mailbeyond.com/restoring-factory-defaults-to-the-cisco-asa5505-firewall-via-the-console

Do you need to bypass the password ->

Factory Default:
ASA = 192.168.1.1

I dont have the console cable available.

I'd like to know how to use the Reset in the back. For example I tried holding it down for 30 seconds but nothing happened.

I think the "reset" button is just there to make us feel better. :)

If you cannot telnet or ssh to the unit, you will need a console cable.

Ok... I borrowed a console cable and successfully reset it back to factory defaults.

Now I need help to:
1) configure the Ethernet Port 0 (VLAN1) to use a Public IP 216.123.2.192/255.255.255.248 DNS1 207.3.65.22 DNS2 207.3.65.32
2) configure the Ethernet Port 1 (VLAN2) to use an Internal IP 10.0.15.254/255.255.255.0

flip-flop your vlan assignments.  i have a problem with the ip address that you want to assign your public interface.  "192" is the network boundary.  my example shows the first usable IP -- adjust as needed.

config t

name-server 207.3.65.22
name-server 207.3.65.32

int vlan 1
 description private network
 nameif inside
 security-level 100
 ip address 10.0.15.254 255.255.255.0

int vlan 2
 description public Internet
 nameif outside
 security-level 0
 ip address 216.123.2.193 255.255.255.248

int e0/0
 description public Internet
 switchport access vlan 2
 no shutdown

int e0/1 description private network
 switchport access vlan 1
 no shutdown
end

That only reflects the VLAN and Ethernet interface configuration with name servers specified.

There's something I didn't mention: can you first help me turn off DHCP for VLAN1 Eth 0/0, then configure the static?

... can we continue on the other thread?
