Recommended network configuration for HA (MSSQL private Sync Network) in W2k12R2

hello

my goal sql-always on group on windows server 2012 r2 high availability cluster. 

each server has 2 network cards. 1 used external communication clients (cluster , client) , 1 used internal communications (cluster only).

i got problem during configuration networks, internal network shouldn't take turn on switch, should go directly without other network hardware in it. 
configured network without gateway, of course wasn't routed. (192.168.14.11/24 , 192.168.14.12/24 hosts) host ping each other without problem.

but when configured cluster, didn't show second network, , when added later, every time, 1 node crashed.

did miss or isn't possible?

thank advide.

hi n0rthclub,

it seems of network settings incorrect,if use iscsi, network adapters must dedicated either network communication or iscsi, not both. if use network iscsi (storage), not use network communication in cluster.
