Dear friends, I need help to set up firewall on my freebsd 5.1 box. I have built new kernel with ipfw enabled and is working fine. I need to know which of the 3 interfaces do I put the natd and ipfw. My freebsd 5.1 box has 2 nic cards. ed0 connects to LAN and ed1 connects to adsl modem. I use user ppp to setup the connection to the isp who assigns dynamic ip address to the tun0 interface. I have no ip address assigned to ed1. I have traffc coming in through the tun0 from outside to the LAN. Which of the interfaces do I use to block unwanted traffic from the internet.- ed1 or tun0? How do I configure the tun0 interface for the firewall since I do not know the interface address before hand? Secondly which interface do I place natd? If anyone has configured adsl with dynamic ip address assigned to tun0 I will like to have some info about how it was configured with ipfw. regds ed -- email: [EMAIL PROTECTED]
