Reset Cisco PIX Firewall 515e

par13 — Mon, 11 Mar 2019 17:29:48 GMT

I just inherited a cisco pix firewall 515e with no documentation or password information. The firewall will need to be reset to factory. Then, after completing this task, start configuring basic information such as interface ip address.

Can you help?

Here is the password recovery procedure:

You would need to know what is the version of PIX to download corresponding password recovery binary file:

http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_password_recovery09186a008009478b.shtml

If you perform the password recovery, you do not need to reconfigure the PIX firewall.

Hope that helps.

Thanks for this response, it was very helpful. As far keeping the configuration of the firewall, I'm not sure that

we can keep these rules. The firewall has so many rules that do not pertain to our environment. It

could create more tech support than starting fresh.

How do I erase all this infomation?

Thanks

There are couple of methods to wipe out device configuration, either use pix(config)# write erase, or use configure factory-default parameter under global configuration see both links bellow.

PIX code 7.x - factory-default

It works!

Now I'm at the point to start using Cisco ASDM and its not letting me connect to the firewall. I prefer using the GUI to configure all security policies than using command prompt.

However, as I mentioned above, it is not letting me connect. it keeps giving me an error "Unable to launch device manager from https://192.168.1.1"

Any ideas?

you need to permit http connection

http server enable

http 192.168.1.0 255.255.255.0 inside

ok, I followed your instructions and still does not work.

After opening the log connection, on the cisco asdm-idm launcher, it says:

Ok button clicked

Trying for ASDM version file; url = https://192.168.1.1/admin/

No version file found

Trying for IDM, url= https://192.168.1.1/idm/idm.jnlp/

Not IDM

It seems like the firewall keeps refusing any connections

sounds like asdm image is not loaded.

can you post "sh asdm image" and "show flash" and "show version"

you are using Cisco PIX Firewall Version 6.3(5). you need to use instead the PDM (PIX Device Manager) not ASDM to connect to web GUI. To run ASDM on your PIX, you need to have minimum i believe PIX OS version 7.0.

After going thru all this trouble, is not easier just to create the rules thru command prompt? Basically, here is what needs to be acomplished,

internal networks:

192.168.1.0/24

192.168.2.0/24

both needs to be able to search internet websites, browse, and connect to other remote networks (ex. 10.5.1.0/24)

On the other hand, a remote network (ex. 10.5.1.0/24) needs to have access to internal network 192.168.1.0/24

Can you provide an example?

Thanks

The config below should allow you to access the internet at least.

nameif ethernet0 outside security0 (This the outside interface)
nameif ethernet1 inside security100
ip address outside ** (Enter your Public IP Provided by your ISP)

ip address inside 192.168.*.* 255.255.255.0 (Enter your Inside IP)
pdm location 192.168.1.1 255.255.255.255 inside
global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
access-group acl_inside in interface inside
route outside 0.0.0.0 0.0.0.0 *** (** This should be your ISP router)
http server enable
http 192.168.*.* 255.255.255.0 inside (*** subnet to manage Web GUI on PIX)
access-list acl_inside permit ip any any

Make sure 192.168.2.0/24 have a route to the PIX.
