Need help with Cisco ASA 5510 Firewall

[thakkardixit]

Hi, I am extremely new to networking with not much experience. We have a Cisco ASA 5510 Firewall and would like to use it for following purpose:

1. Use it like a router with internet connection from Optus coming in.
2. Link it with our existing network, so any PC connected to the ASA can get internet connection plus the network devices.
3. Setup VPN, so people can connect remotely through this firewall.

Can I achieve all of the above? If yes, how? Any help would be greatly appreciated. Thanks.

Yes it can do all of this.  If you use the ASDM GUI it has wizards which can achieve all of this.

Hi Philip,

Thanks for your quick response. However, that's the issue. I can't get the ASDM GUI working. I can putty in though, so will have to rely upon CLI. Any doco or instructions that I can refer to and follow it? Thanks.

[Philip D'Ath]

From the CLI do a "dir flash:asdm*" and see what (if any) ASDM images there are.

[thakkardixit]

Here's what I get when I typed dir flash:asdm*

Directory of disk0:/asdm*

99     -rwx  16280544    10:58:12 Oct 01 2012  asdm-645.bin

260034560 bytes total (196894720 bytes free)

What does this mean?

[Philip D'Ath]

We need just one more bit of info now.  Can you attach the current running config.

[thakkardixit]

Attached.

Please advise how do I go about it. Thanks

[Philip D'Ath]

You'll need something like:

asdm image disk0:/asdm-645.bin

Then point your web browser at:

https://10.2.10.25/

[thakkardixit]

When I type that command, I get this msg:

ADMASA01# asdm image
                   ^
ERROR: % Invalid input detected at '^' marker.

I can see the file asdm-645.bin is there in disk0:/.

What are we trying to do here?

Also as you saw the current firmware ver is 8.2. Should I update it to 8.3? Will that help?

[Philip D'Ath]

Go into config mode first.

config t

[thakkardixit]

Pardon my ignorance Philip. Ok I went to config terminal mode and typed that command, however nothing happened either. Just remained on the prompt !

Not sure what am I doing wrong here ! I tried to start ADSM through web page - https:\\10.2.10.25/admin and followed the prompts to install java etc. But it says "Unable to launcd device manager". Any other suggestions? Can I call you if you are in Australia? Thanks.

[Philip D'Ath]

I'm not in Australia.

When you use PuTTY do you connect to 10.2.10.25?  If not, what do you connect to?

[thakkardixit]

Yes I putty (SSH) in through 10.2.10.25. Another way I am able to connect is via console cable through putty - serial. Both gives me CLI.

[Philip D'Ath]

Your software is quite old.  Try adding this as well (and then browsing to it):

asdm location 10.2.10.0 255.255.255.0 management

[thakkardixit]

which software? Do you mean the firmware? Should I upgrade it to latest version?
