===== What's the difference between BSDRP and OPNsense or pfSense ? =====

  - The main goal of BSDRP is not firewalling but routing. If you are looking for a firewall, or for sharing your Internet access, don't use BSDRP but use [[http://www.pfsense.com/|pfSense]], [[https://opnsense.org/|OPNsense]], [[http://smallwall.org/|SmallWall]] or [[http://t1n1wall.com/|t1n1wall]], instead.
  - BSDRP doesn't have a Web GUI: It's to be configured from a CLI only (like Cisco/Juniper), or by an API (like netconf) [planned feature] 
  - BSDRP is not intended for home use but for company use (small ISP as example).

===== What's about the routing performance ? =====

It depends on your hardware:

  * 4 cores Atom with with multi-queue aware NIC is the minimum for a line-rate gigabit router (1.48Mpps of smallest packet size).
  * 8 core Atom not enough for the minimum for a 10Gigabit Full-Duplex (10Gbps receiving + 10Gbps transmitting = 20Gbps) with IMIX packet size distribution
  * 8 core Xeon is enough for a 10Gb line-rate router (14.8Mpps) 

===== What's about the firewall performance ? =====

==== 10Gb/s hardware ====

==== 40Gb/s hardware =====

A server designed to support 40Gb/s of bidirectional traffic could almost support IPFW in stateless mode but not pf neither ipf:

===== What's about IPSec performance ? =====

It depends of your hardware and crypto algorithms used:

===== What's about different VPN performance ? =====

===== Can I install BSDRP on a MIPS or ARM device (RouterStation, D-Link, etc..) ? =====

BSDRP targets x86 architectures only.

[[http://zrouter.org/|ZRouter.org]] targets ARM and MIPS architectures.

The technical issues regarding the support of ARM/MIPS architectures with BSDRP are:
  - Be able to modify the bootloader (for changing the boot-partition) from the FreeBSD user space: Permit to switch the active partition after an upgrade
  - Having a bootloader that support a minimum boot-partition selection screen: Permit to revert-back to the previous version if the new installed version has major problem.
===== Can you add squid/apache/BitTorrent server/subversion/MySQL/etc. to BSDRP ? =====

All features not related to routing will not be added into the base of BSDRP ([[Documentation:End-users docs#system|but installing or removing FreeBSD packages is still possible]]).
===== Where is the forum ? =====

No forum planned..
