Using a Cisco 806 router, I want to block all outbound e-mail traffic from the LAN except for that from one IP. In addition, all denied outbound e-mail traffic is to be added to the syslog.
LAN IP's: 192.168.1.1 to 192.168.1.254
Router IP: 192.168.1.254
IP Allowed to send e-mail: 192.168.1.100
I think I have an idea on how to do this, but would like some help from the experts first.
