SOLVED No connectivity from within jail

[eroji]

I am running a test FreeNAS 9.3.1 (latest) instance as a VM in ESXi 6.0. Everything seems to be working just fine until I added plugin jails (plex, transmission). I am able to ping the IP of the jails on my network, however, the jail themselves are unable to resolve/ping to anything. I confirmed that the gateway and DNS has been set correctly. After doing some research, it appears a number of people are having similar problems when running FreeNAS in ESXi. Some tips were to change the security settings on the VM network. I tried that and that seems to work, for a few minutes only. Soon after, it would lost connectivity once again, which seems to indicate it may not be a ESXi networking issue at this point. I also tried changing the network from regular vSwitch to dvSwitch, both of which behaves the same way.

The specs of the server are:
Supermicro X10SLM-F
32GB Samsung DDR3 ECC UDIMM
M1015 flashed to 9211-8i HBA
4x2TB 7200RPM Hitachi/Toshiba HDDs
Crucial M500 480GB
Samsung 830 128GB
