The filtering will take place between two ethernet gigabit interfaces. Also, what kind of ethernet fiber SX gigabit interface is recommended for production use? I need to continue maintaing high uptime and stability is primary concern, also it need to perform well and of course the driver must work well. How many NMBCLUSTERS do I need for a bussy 1 gbit ethernet filtering bridge or router? Other kernel issues to keep in mind? I use ipf for ip filtering. I was also wondering if there exist any dual fiber gigabit ethernet cards (two fiber-pairs on one card) in order to save pci slot space. I will be grateful for any hints or comments.
