NAT rule between two WANs

SEBASTIANSEBASTIAN Newbie
in Mid Range Firewalls

Hi!

Is there any way to do this configuration?

I need to access ROUTER ISP 2 (192.168.2.1) by HTTP, coming from "HOME" and passing through ISP 1, ROUTER ISP 1 (20.20.20.20), X1 interface, X2 interface.

X1 and X2 are WAN interfaces. X0 is a LAN interface.

I have tried some NAT rules but there is something I am not doing right.

Here it is a simple, but clarified, network scheme:

    Hi @SEBASTIAN ,

    You can achieve your goal through SonicWALL Policy based routing.

    Sorry, but I did not mention Router 1, X1 and X2 are all doing NAT.

    Hello @SEBASTIAN

    You would need some sort of VPN set up on ISP Router2 to be able to directly talk to the private interface of that device after going through ISP1 and the cloud to get to the edge of that network. Your public IP source would be related to ISP1 and you can't get to private 192.168.2.1 IP space just by routing through ISP router2

    Can't you port forward from firewall ISP1?
