I m trying to set my friewall in my network.
The network is very simple.
I have my router in 192.168.16.1 255.255.255.0 (mac-address 58-98-35-2a-4c-39)
I have my switch in 192.168.16.26 255.255.255.0 (mac-address 00-19-99-5d-1f-43)
and i have my firewall ASA between the router and the switch in 192.168.16.250 255.255.255.0 (mac-address 64-9e-f3-ba-28-c9)
So i need to configure 3 interface in my ASA.
- OUTSIE e0/0(I call it INTERNET)
- INSIDE e0/1(I call it LAN)
- MANGEMENT m0/0(I call it MANAGEMENT)
The interface management is well configured. I enabled http access and i can access to my ASDM inteface form all my network
ip address 192.168.16.250 255.255.255.0
Now I would like to plug my firewall in the network.
My router in e0/0(INTERNET) and my swtich in e0/1(LAN)
I understood that in transparent mode I have to config interface INTERNET and LAN with mac-address.(asa 5510)
So i did as follow.
But with this config when I plug the firewall, i dont have access to internet anymore.
What I did wrong?
Of couse you are missing something.....
You do NOT have an ip address assigned to your ASA..
Now you are running 8.4 so as one of my colleagues one said:
In version 8.4(2) or prior versions, the ASA uses the concept of bridge-groups in transparent mode. Therefore, you need to add the interfaces to a bridge-group and then configure the IP address under the BVI. See here for a config example:
