Ubuntu

any limitation on IP tables?

Asked by Wah

Hi

I'm new with Ubuntu. I'm plan to use Ubuntu for IP filtering and bonding. I would like to know if there is any port limitation ( # GigE ports) that Ubuntu supports for IP filtering and bonding. I'm thinking of 10 GigE ethernet ports.

HW - Intel Duo Core - 2.3Ghz, 2Ghz RAM and LAN Chip Intel 82753L

Thanks

Wah

Hello..

This article gives you more info on iptables..

https://help.ubuntu.com/community/IptablesHowTo

I can bet you that on a default install when you run the command

sudo iptables -nL the result you get is

Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

=all traffic allowed ;-)

Iptables is an IP filter, and if you don't fully understand this, you will get serious problems when designing your firewalls.. ;-)
