show asp table socket


Protocol  Socket    Local Address               Foreign Address         State
SSL       000035c4  192.168.100.3:443            0.0.0.0:*               LISTEN

Hi,


It seems that you are opening port 443 and 22 on your ASA. This can be checked by using below commands:

- show run http

- show run ssh


I don't think by default it will show any open port. This is because by default the behaviour on ASA is that all ports are close and you have to open port that you want to open/use. Which on router, it's the opposite, by default all ports are open.
