Unable to access Juniper Jweb from fxp0, but can on ge-0/0/0?

Im new to Juniper and trying to configure Jweb access on a vSRX.

I've enabled fxp0 and assigned it an IP and enabled HTTP web-management. The IP is on the same subnet as the rest of my IP's on my network. (No security zone assignment as that is not possible on fxp0).

I tried to load the Jweb page via internet explorer but it wont come up.

When I tried to assign the IP address to interface ge-0/0/0 and put that interface in the trust zone and assigned it the web management IP, I can successfully load the internet explorer page.

​

Why wont fxp0 load Jweb but the ge-0/0/0 will?
