How can I do this? I think it's NAT.

I have two sites connected with USG20s, let's call them Network A (10.0.0.0/24) and Network B (192.168.1.0/24). Network A has a server that sends out a UDP packet to 10.0.0.201. I need to make that packet go to 192.168.1.7 but I am having no luck. Any ideas?

10.0.0.201 is within Network A (10.0.0.0/24 ) so it will not go over the WAN to the WAN of Network B (192.168.1.0/24).

Their might be a another way if you can send out a UDP packet to 10.0.0.xxx to a virtual interface on 10.0.0.0/24 say 10.0.0.254 you then do a NAT rule to the WAN of Network B and routing rule to SNAT from Network A WAN of the traffic.

Then Network B NAT to 192.168.1.7

Yeah, for reasons, the packet is hard-coded to go to 10.0.0.201. I was thinking of a virtual server/interface that then translated to 192.168.1.7 and sent through the tunnel but somehow, I am just not sure I am doing it right.

PeterUK

The virtual interface way would work as long as you don't have a device with 10.0.0.201

So Network A virtual interface 10.0.0.201 on 10.0.0.0/24

NAT

incoming interface like LAN1

external IP User Defined 10.0.0.201

internal IP User Defined the WAN of Network B

port mapping the port its sending out to.

Routing

incoming interface

member like LAN1

service the port 10.0.0.201 is sending

next-hop

type interface

interface like WAN1

source network address translation outgoing-interface

on Network B

NAT

incoming interface like WAN1

external IP WAN1 address object interface

internal IP User Defined 192.168.1.7

port mapping the port its sending out to.
