**Questions about Unix / Linux Servers which are running Network Protocols or a Firewall –**

Questions about firewalling or network protocols such as OSPF running on linux / unix servers... to qualify under this category:

 - The system *must not* be purpose-built by a vendor specifically for routing / switching / firewall purposes
 - The system *must not* have commercial support option for the required routing / switching / firewall function 


Example questions:

 - http://networkengineering.stackexchange.com/questions/2660/ospf-lsa-checksum-error
 - "How do I configure `iptables` to rewrite to a different TCP port?"


I personally think these should go to serverfault, but I hope the community will vote on the matter.  If you want things such as an IBM server running Quagga to be on-topic, upvote.  If you agree with me, downvote :-)
