I am installing new firewall , and I am having vpn tunnels coming over to 2621 routers . I want to move away couple of tunnels to firewall.
But i dont want to nat tunnel traffic , also I want to configure firewall such as tunnel traffic is allwoed to access all the services in my internal network but external traffic is not allowed any services on my internal network.
Re: help me with asa installation and firewall rules
We should have a public ip address for Firewall interface.Once that is done configure the peer interface address as the address of the firewall instead of the router.By default firewall doesnt allow external traffic to use the internal resources.
