Dell Switch 6248 - cannot connect to firewall with configuration

I have it so the Vlan's can talk to each other, the tracert shows that they're going through the correct default gateway's. The issue I'm having is that on port 47, I have the wifi firewall connected to VLAN 50, which has the IP of 172.10.10.2. The Wifi Firewall's default gateway is set as 172.10.10.1.

I can ping the default gateway of the VLAN 50, but not 172.10.10.1; Even with the ip route command below.

Any help will be greatly appreciated.

Here's my running configuration:

!Current Configuration:
!System Description "PowerConnect 6248, 3.3.8.2, VxWorks 6.5"
!System Software Version 3.3.8.2
!Cut-through mode is configured as disabled
