Source NAT Forwarded Ports

Product Discussion
1

I have a Peplink MAX BR1 Mini that I have forwarding ports to a device behind it, but I am not getting a response from that device. I see the traffic hit the device’s interface but since it is Layer2 it can not send the traffic back b/c the traffic appears to come from the Wan interface of the network sending the message.

Can I source nat the traffic while forwarding that port so that it appears to come from the LAN interface of the Peplink instead of the originating address?

@lcwsa ,

The device behind having default gateway to the BR1 Mini ? Supposedly for normal port forwarding we don’t perform the source NAT.

Do the device behind enabled with endpoint firewall which blocking the traffics ?

Thank you
