I have one valid IP address for my Gateway's external NIC, one valid IP address for my DMZ(just web server), and Using NAT(hide mode) to convert internal localnet invalid IP addresses to Gateway's Valid IP address. I allowed localnet to access Internet from Firewall.     But there are some problem I met:     1. I could connect to the internet from any of my localnet when I power on it. But when I used it sometimes, such as connecting 10~20 website. The connection stopped. But When I repower on it. It work again. And running sometime, it stop again. Why?     2. Can I using command "ping" in my localnet?     best regards     Tom Zhang
