Making this work with Cisco ISR router

[Guest]

So I recently set up Endian on my company network which uses cisco switches and a 1921 ISR router. I first set it up behind the L3 switch, which worked fine for certain parts of the network. I now would like to set it up for all of the company network and want to put it between the router and the L3 switch.

Code:

Router--->Endian---->L3 switch (DHCP server)--->L2 switches and some hosts

But when I do this set up. I was not able to get on the internet.
At the same time, I am not sure what I need to change for my Cisco router to make this work.

Can someone please let me know if there are any sample config that I can start off with to make this set up work? Especially the config for the router and Endian.

Thank you!
