Not sure about ssh, but NFS has editable config files in /etc that can
be IP address specific, if you're using DHCP to specify IP addresses,
they can be specific to MAC address hence specific to NIC. Perhaps ssh
is the same. Check /etc/exports if this is a server or /etc/fstab if a
client to see if the IPs jive with ifconfig, /etc/interfaces, or however
you configure your NICs.
