Sonicwall 4650 WAN port to Force10 S4810 over fibre module

Hi Everyone,

Hoping someone might know why this particular pairing does not want to communicate.

The setup:

Subnet: 10.0.0.0/21

S4810 - Port 37 has Dell 10Gbit SR fibre module

Sonicwall 4650 - X24 has Sonicwall 10Gbit SR fibre module

X24 is configured in WAN zone with Static IP Address 10.0.0.9

S4810 has a VLAN 3 configured as untagged on port 1-6, and tagged on port 45 to 48 which connect to further downstream switches. Equipment on ports 1-6 are Hyper-V Servers running a number of virtual machines.

Sonicwall Port 37 on S4810 is configured as switchport and portmode hybrid with no shutdown

VLAN 3 on the S4810 has an IP address 10.0.0.22. Port 37 is added to VLAN 3 as untagged port.

My issue is that after configuring the Sonicwall X24 port with Static IP and connecting the fibre cable between the Sonicwall and the S4810, it is unable to ping any device on the 10.0.0.0/21 subnet from it's diagnostic pages. Also none of the other devices on the subnet are able to ping the WAN port 10.0.0.9 of the Sonicwall. I even made sure ping was enabled on the X24 port.

I have checked the cable and it lights up on either end and the Sonicwall page reports that full duplex 10Gbps connectivity is found.

This Sonicwall is acting as it's own little isolated pocket from the rest of this network due to security requirements to have IPS and some firewall control of traffic coming from devices connected to the sonicwall to the subnet 10.0.0.0/21. The Sonicwall's lan side is running on a different subnet with rules and services in place to filtering outgoing traffic.
