Allow website using its IP?

[vinayak]

Dear all,

I am having Cisco ASA 5510. i blocked all  web traffic for my LAN Users. & allow them only to access google.

Now i want them to access http://164.100.111.5:8080/mahabhulekh/  this website..

How i allow this?

[Jennifer Halim]

Here is the access-list to allow them:

access-lits permit tcp any host 164.100.111.5 eq 8080

[vinayak]

Dear Jennifer,

Its not working.

[Jennifer Halim]

Can you share where you apply the access-list and which interface is the traffic from?

Also, the access-list needs to be applied above any "deny" ACL that you might have.

[vinayak]

here is the config

It should already work without adding any configuration. As per the current configuration, you should be able to access any websites. Is this correct?

[vinayak]

Hi jennifer,

Currently i made 1 object group & members of that group only access to any website.

Rest of all have access only to google.com

I want all my LAN Users have access to http://164.100.111.5:8080/mahabhulekh/ &     http://mahabhulekh.mumbai.nic.in

websites like Google.com

[Jennifer Halim]

Well, from the above posted configuration, you have not assigned the HTTP policy to the global_policy, so it will only check on the access-list applied to your inside interface. The access-list that is applied on your inside interface is allowing everyone from your LAN to access the Internet.

So if you test it now, everyone from 192.168.0.0/24 should be able to browse to anything with no exception.

Have you tested it from your LAN users? what is the ip address of the PC where you are testing it from? Can you access any websites at the moment? you should, as there is no rule to block anything as per the current configuration posted earlier.

[Kureli Sankar]

I see one problem:

static (inside,outside) interface server netmask 255.255.255.255

Pls. remove that line.  You cannot do 1-1 static to the interface IP address. You can only do static PAT

change it to the following if the server listens on tcp 80

static (inside,outside) tcp interface 80 server 80 netmask 255.255.255.255

Repeate the above line for any other ports.
