MMS Communication to be established between two controller with diffrent series of IP address. One Controller is having IP address 172.16.1.61(5SP2 Version) and other controller is having IP address 172.16.88.151(5.1 Revd).
Is it possible to establish MMS Communciation between these two controller with some settings change in RNRP.
Yes, but you need to use some form of Network Address Translation other than RNRP. A router ( or a firewall with a built in router ) can do this for you.
See these questions ...
In your case (I assume) you are doing AC800M to AC800M so you dont have the issues about Sattline IP address handling, but the RNRP principles are the same and it does work very well.
