That's what it was. For some reason, the new system doesn't like the hub and moving the connection to a switch, and using port mirroring is working. 
  
If it didn't have any connectivity at all, could it have been a speed mismatch?

 The other option is to attach the hub to the span port and attach the
 
 monitor devices from there. You allready have the equipment for that.
 
 This does not interfere with the normal trafic and if your monitoring PC is
 not sending and data (reverse dns queries?) there should also be no
 collisions.

 Are you sure you want tu run all traffic through a hub? This might lead to
 packetloss due to colissions.
 
      
 It's a temporary setup so that we can get a number of services going right.
 So far, we don't see any packet loss or terrible quality loss and we're even
 passing voip calls through the setup.
 We were using a switch with port monitoring but because we had multiple
 devices which needed to monitor the traffic, we ended up using a hub for
 now.
 
 The setup I'm talking about is...
 
 WAN-Routers----Hub----Firewall----switches----etc
 
 The wireshark and other monitoring systems are connected to the Hub.
