Use NAT to connect two non-routable network

yes, you can NAT to a non-local address, and you can control whether LTM responds to ARP requests or not.

 

 

Autolasthop only helps on the response, not getting to the destination.

 

 

You'd have to be careful of L2 & L3 loops, of course, as always, but if they just need to talk to each other, you can connect them via a private subnet on its own vlan, either with a crossover cable or an intervening switch. We have long recommended that practice for redundant pairs, esp if you are mirroring persistence or connections, might work for a simple comm channel between 2 pairs just as well.
