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.

 

 

 

 

Where can I found the doucment that support this usage? I had read the section about NAT for the configuration guide but found that it is too vague on this issue. We need some 'prove' to convince our service provider to set this for us.

 

 

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.

 

 

 

 

It would be great if those 2 subnet is directly routable but the 2 set of servers and LTMs are located at 2 different site(they will backup each other), so we are not able to make a direct connection for them.

 

 

Thanks for you helpful response
