Firewall Configuration PKT


Good evening!


I'm writing to you today in need of some assistance. I am currently working on a task configuring two networks that can communicate safely with eachother through the use of a firewall. Both networks are working fine individually, however, when it comes to communicating across to the opposite networks the packets fail.


I ran a trace route to see where the issue lies and it seems to be at the routers of each network. I'm unsure on how to get the firewall to become operational and send packets between the networks successfully.

I'm assuming I need to configure VLANS 1 and 2 on the firewall but my knowledge is lacking. Does anyone have any tips?


Attached is a link to the toplogy.

Thank you!

How are the routers on each site supposed to route traffic to each other?  Are you using OSPF, static routes, some other routing protocol?

On the ASA, did you create rules on eth0\0 and eth 0\1 to allow the required udp\tcp ports from the appropriate ip address ranges?  On the ASA, do eth0\0 and eth0\1 have the same security level?  If so have you enabled traffic between two or more interfaces which are configured with the same security level?


Afternoon Jeff,


Both routers have static routes. I don't believe I have created the rules you mentioned. I'm pretty new to networking so I'm just trying to rack my brain. As far as I am aware, and this may be incorrect, I need to configure both VLAN 1 and VLAN 2 on the ASA to allow traffic to pass through? I am, however, unsure what the IP configurations of the inside and outside interfaces would be.


I'm sorry if the information I provide is pretty basic, I'm just trying to understand how to achieve the following:


"Install and configure the firewall to provide the secure link between the two networks."
