Network Extension via two UTMs

Just to start, I am a complete n00b on VPNs and am trying my best to learn, however I have been put in a position to solve a problem quickly, so here goes.

I am needing to connect two geographically separate LANs via bridge and maintain the same IP space on each. I setup two software UTM 9s on a ESXi host to work with for proof of concept. What I HAVE been able to accomplish is build RED tunnel or an IPSec tunnel between the two and allow different networks to communicate, but I need a single network to span them both. 

Is this even possible with UTM 9s in a software only configuration?

I have tried bridging the redsX and eth1 interface on one and trying to get the other to manage the network via this post: https://community.sophos.com/products/unified-threat-management/astaroorg/f/62/t/57348
with no luck.

Any suggestions?

    The only tool I've used to watch the actual packets is tcpdump, with an occasional packet cap that I've analyzed with Wireshark.
