Pfsync: crossover or switch?


  • Netgate

    Is it considered best practice to use a couple switch ports on a blank VLAN or a crossover cable for pfsync given only two failover nodes?


  • Rebel Alliance Developer Netgate

    Either way is fine. Over the years we've found some NICs can be picky about direct connections so a switch can sometimes be more stable, but generally speaking a simple crossover is fine unless you have issues with it.



  • I've set up replicating SANs before and I've always just used a crossover cable for the synchronization interface.  I don't trust another piece of electronic equipment in the mix for no reason, and I've never had a problem with direct-connected interfaces.
