[opensuse] Firewall with a dynadns router behind it
I want to get a router that supports dynadns but I want set up a computer with a firewall using iptables to be my firewall to the internet modem. So now in the router options it says to put the internet IP address the modem has..... Okay so the lay out CABLE MODEM -- FIREWALL using IP tables ---- Router --- workstations Now if I use the firewall pc as a DHCP, that would not give the Router an internet IP, right? It would be a local IP. So....could I refverse it and put the IP tables behind the router and use the router as a dhcp and make the firewall static? i.e: CABLE MODEM -- Router -- FIREWALL using IP tables -- switch -- workstations Keep in mind this is a wireless router w/ 4 LAN ports as well... So in the 2nd scenario I wouldn't need a wireless router I could get a wirless switch, right? Actually, I guess in the 2nd scenario I wouldn't even need the router? Another question is, in first scenario, would the firewall PC get connected to the Router's internet port (is that uplink?) or into one of the regular ports. In the 2nd, would the firewall pc go into the switch uplink or a switch port? -- Michael S.

My eight port high speed switch has a specific uplink RJ45 that attaches to the eth0 nic card of my [firewall, NAT] box. My five port high speed switch does not have a specific uplink port... any one of the five RJ45 jacks can be used as the uplink--- doesn't matter. See you owner's manual for the switch... if the back of the switch has a jack labled uplink its a safe bet that you should use that one...

It doesn't matter what switch port you use. That "uplink" switch/port is used when connecting to another switch or hub and requires one of them to be cross wired. Otherwise, you'd need a crossover cable to connect two switches or hubs. Since he's connecting to another NIC in a computer, a crossed connection is not needed. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
