routing – Sonicwall TZ105 Site to Site VPN Created can ping gateways but can’t ping network from other site

Need help here

Site B

TZ105 
x0 Lan 192.168.162.1
X1 WAN 64.x.x.x
X2 LAN 10.0.3.1

Site A

TZ300
X0 LAN 10.0.1.1
X1 WAN 69.x.x.x

VPN tunnel set up as VPN SITE TO SITE and is Green

From Site A I can ping 10.0.3.1
From Site B I can ping 10.0.1.1 and everything else on this network

From Site A, I can only ping 10.0.3.1. Although I cannot access a single service, VMConsole, or anything else on the 10.0.3.0 network. I understand that firewall needs to be able to allow for ping on 10.0.3.0 network.

Any ideas?

SITE B
Secondly, I’m going to be connecting up a VOIP/SIP network onto this router for Site B. Do I need to create a VLAN for the Phones? Do I need to create a VLAN for the 10.0.3.0 network?
