We want to change internet traffic using an unused cox modem line. Internet only.
This network has stores that need to come in VPN and have Credit card processing traffic. That was affected when we tried to change internet gateways. I want to know why.
As of right now internet traffic goes through an ASA 5510 fw.
We will like to make use of a Linux installation to work as the internet firewall. The Cisco ASA 5510 already has other functions such as VPN with store traffic. Credit cards come in through the ASA firewall.
The network has OSPF as dynamic protocol. The Firewalls are part of the backbone area 0. There is also OSPF area 10 for our main office and backup DR location. LAN traffic at OSPF area 10.
I take it internet access is at backbone network,
I think the ASA firewall needs to know about the new Linux firewall as internet gateway. Not sure if the admin made that entry.
The Linux firewall needs to authenticate with the OSPF network. I see that it did yet did not have the network entries in the quagga daemon.
There is also a core router in between LAN and the Backbone that points to the ASA firewall for internet.
In the Linux firewall in the quagga folder you have a zebra config file with entries as well. I wonder if that file is also needed.
I am attaching a page with the config and network dumps.
Thank you in advance for any help.
