Cisco 5505 security plus configuration

sebastienlex — Fri, 21 Feb 2020 15:51:52 GMT

Hello,

My name is Sebastien
My english is not perfect, i'm not natif of this language so i going to do my best.

I received my Cisco ASA 5505.

My knowledges in network Cisco and in general is very low so i have lot of questions, but for this time being i would like to focus on a problem with ASDM.

I used the factory configuration with the command : configure factory_default 10.1.99.254 255.255.255.0

and i put settings on my network card with this one : 10.1.99.2 / 255.255.255.0 and 10.1.99.254 to be on the same network.

so after this operations i opended my browser and i writed : https://10.1.99.254:443 and i downloaded and installed java and ASDM but i had a problem.

usually when i write on ASDM my address : 10.1.99.254 the loading turn off at 52% and i don't understand the ASDM close the programme like this video show it.

i looked on internet but i didn't find answere.

hi,

could you post a show version output?

the 5505 ASA code should be compatible with ASDM image.

https://www.cisco.com/c/en/us/td/docs/security/asa/compatibility/asamatrx.html

there might be also a java compatibility or runtime issue that you should be aware of.

your ASA code and ASDM image should be compatible.

https://www.cisco.com/c/en/us/td/docs/security/asa/compatibility/asamatrx.html#id_59423

do you have HTTP/ASDM configured on the 5505?

could you post a show run http output?

Ok, it's not clear ...

So i decided to do a new configure

I have internet ! it's work but, it's impossible to connect to ASDM

what do you think about that ?

ciscoasa(config)# configure factory-default 192.168.2.5 255.255.255.0

If you can SSH just add
http 192.168.2.0 255.255.255.0 inside

The reason you can't ASDM from outside most probably reside to your ISP or the equipment that offers you Internet NOT NATTING 443 toward ASA outside IP.
