Can't connect UTM eth1 to DHCP server

Trying to setup my first homelab and I have been unable to get Sophos UTM to get an IP from my modem.

I have 4 physical NICs, and have two vSwitches setup. vSwitch0 uses NIC #3 and is the internal network. vSwitch1 uses NIC #4 and is connect directly to my cable modem. I have a separate portgroup for each.

For my UTM VM, I have both portgroups (for vSwitch0 & vSwitch1) as network adapters (eth0 & eth1). eth0 works fine, and the link and state are up. eth1 however says link up and state down with an ip of 0.0.0.0 and default gateway of 0.0.0.0. I thought it was the modems issue, so I turned the modem off, booted UTM, and then turned the modem back on. Tried to renew and nothing.

For kicks I plugged NIC #4 into my router, restarted UTM and tried to renew again, expecting it to receive a 192.168.1.x address with a default gateway of 192.168.1.1. It did not, still all zeros. The only way I could get eth1 status to be up if if I set a static IP in sophos for that connection, it will not get an IP address automatically.

My router's web interface shows that there is no connected ethernet devices, the ethernet lights are lit up on router & server, cable is known good. Sophos logs look like:

Whats going on? Any idea how I can fix/configure this? I need sophos to connect to my modem so I can use it's firewall features...etc I imagine if I can get it to automatically recieve na IP from my router, I should be golden and it will receive one from my ISP through the modem
