I am thinking about building a pfsense-based router and would like to use a couple different interface types. This may seem like too much work but it would be a great learning vehicle.
One question I have is which interface topologies support direct connection between two NICs without an intervening router? I understand that 10Gbase-t allows this but what about 1Gb ethernet, SFP+, QDR, etc?
Another question is: are any obvious technical issues looming if I get the direct connections to work other than needing a powerful enough processor and enough PCIe connections to support the communication? I don't know how many concurrent connections would need to be supported but let's assume more than 5 10gig connections at once.
I would also like to originate several simultaneous VPNs from this router - any advice on what would tend to help that (to avoid processor support being the bottleneck)?
Any thoughts would be appreciated --
Dave
