There some marketing scams out there that some ISP use to get you to pay just a bit more for service. One common scam is as follows:
consumer: "I have two computers. I need to make sure they can both get on the internet." (Thinking: "I know my buddy did this with his setup") ISP: "Oh you mean you need a second IP address, right?" (Thinking: "The poor guy doesn't know he can do it with one and NAT server. But I ain't telling him that.") consumer: "Will that let me get both of these connected?" ISP: "Oh you bet. It will only be $5($10/$15/maybe even $20) more dollars a month" consumer: "Ok set it up. Lets do that. I really need to get these two on the internet." ;) Matt ----- Original Message ----- From: "Vulpes Velox" <[EMAIL PROTECTED]> To: "Marwan Sultan" <[EMAIL PROTECTED]> Cc: "FreeBSD questions List" <[EMAIL PROTECTED]> Sent: Sunday, December 07, 2003 8:50 PM Subject: Re: NATd question > On Sun, 7 Dec 2003 19:56:14 +0300 > "Marwan Sultan" <[EMAIL PROTECTED]> wrote: > > > Hello Everybody, > > > > > > Im on FreeBSD 4.8-R fresh installation. > > and this is the configuration i will use on my LAN > > > > Internet ->connected-> DSL Router -> FreeBSD box -> HUB -> LAN > > > > DSL Router has an IP 192.168.0.1 and the real IP too. > > > > FreeBSD box has 2 NIC's > > My question is: > > > > Where and How to sign 2 IPs for 2 NICs? > > > > which IP the NIC connected to DSL should sign? > > Which IP the NIC connected to HUB should sign? > > Which of these IPs will be as gateway IP the clients will sign? > > The DSL connection is probally going to be DHCP so just set the nic connected to > it for DHCP.

The usual subnet mask is 255.255.255.0 so thus there are > 256 possabilities of address in the alloted space.
