Two things... First, I fail to see what this has to do with GNU/Linux. Sounds more like advertising to me. Second, a firewall and a NAT device is NOT the same thing! Amazing how many make mistakes like that... as well as calling a firewall/NAT combo a router. I have several computers on public IP addresses behind firewalls and it works just great, and the firewalls do their job and keep unwanted traffic out. A firewall allows or blocks packets based on a set of rules. (A stateful firewall will adjust its set of rules depending on previously allowed traffic.) A NAT or NPT device will generally be set up to allow any traffic from the inside out, but only outside traffic back in if it finds a match in its address/port translation table. (A side effect of this is that it also provides rudamentary firewalling.) A router passes traffic between different networks based on its routing table, and can be configured to drop certain traffic by setting it up so that it forwards traffic intended for a specific netblock to an IP address that cannot be reached from the specified interface. A DHCP server gives out host configuration data such as host IP addresses and DNS server addresses. -- Michael Kj�rling, [EMAIL PROTECTED] - http://michael.kjorling.com/ * ASCII Ribbon Campaign: Against HTML Mail, Proprietary Attachments * * No bird soars too high if he soars with his own wings. -*- SM0YBY * To unsubscribe from this list, please email [EMAIL PROTECTED] & you will be removed.
