When you create zone, the vlan of public network is optional you should be able to 
Safely ignore it. What's exact error you suffered?

Do this:
1. login your SSVM
	1.a go to the host where the SSVM is running
	1.b ssh -i  /root/.ssh/  -p 30922 link_local_ip_address 
	       The link local ip address can be grabbed from SSVM page on UI which starts with 169
	1.c try to mount your secondary storage to somewhere in your SSVM
	1.d if 1.c won't work, check if you can mount secondary storage on the host where SSVM running.
If failed, then it's your network issue
	1.e. if it works on your host, try to figure out any ip table rules in host blocking NFS
	1.h check routes of SSVM by 'ip route', the traffic to secondary storage should go thru storage
network which is (private IP range in you case
