Hello
I have 5 public IP’s on WAN 1
I have a separate isolated VLAN running DHCP created and assigned to LAN port 2
I have an NVR on LAN port 2 with a local DHCP IP reservation for its WAN MAC
Can I assign one of the public IP’s to LAN port 2 so that all traffic in and out is on that specific public IP? I will also do some specific port forwards for remote viewing on the camera app
Thanks and Happy New Year
Hi James,
Yes, by using NAT Mapping. Just you will assign WAN IP not to a LAN port but to specific LAN/VLAN IP Network. As example VLAN subnet is mapped to WAN second IP address:
For the Port forwarding it is the same. Select specific Inbound IP address for the forwarding rules:
@Saulius_Saltmeris thank you for the reply
Because this is new to me I have a few additional questions
If I do a 1:1 NAT MAPPING to the specific LAN/VLAN am I correct that all traffic from the NVR will be sent out the selected WAN IP and all outside traffic to that IP will go to the NVR?
With the 1:1 NAT MAPPING am I correct that I will still need port forwarding to actually reach the NVR from outside?
If I do a NAT MAPPING to the whole subnet am I correct that all traffic from any device behind that specific LAN/VLAN will be sent out the selected WAN IP and all outside traffic will reach the devices as long as I have the correct port forwards to the device LAN IP’s?
1 to 1 NAT for your case refer to 1 Public IP NATed to the 1 NVR device.
Seeing you have 5 Public IPs, you need to add the other 4 IPs at the “Additional IP Address Settings” under the WAN interface setting.
After you add in the additional IPs, the IPs will showed 1 to 1 NAT option for settings.
You can now configure the Inbount NAT & the Outbound NAT 1 to 1 NAT for the NVR device.
1 to 1 NAT and Porr forwarding are two different NAT method & you need to choose 1 method only.
For 1 to 1 NAT refer to 1 Public IP mapped all ports to 1 NVR device & for outbound you can choose which IP to use.
For port forwarding, usually it will be use for limited public IP and you need to share the same public IP for the multiples NVR devices. You need to make sure each NVR will have different ports mapped.
Same as 1 to 1 NAT, you can choose which IP to use for the outbound and it’s depend the application requirement whether inbound & outbound need to run using the same IP.
If I understand you correctly, this question refer to the question 1 for the additional IPs for the WAN settings. If you refer to /24 network, you need to make sure you have enough /24 public IP NATed. As explained in item 1 ,2 ,3 , 1 to 1 NAT & Port forwarding required you to configured the outbound need to use what IP address depend the application requirement. Some application can have inbound & outbound connections using different IP addresses.
Hope this explained your questions
@Saulius_Saltmeris, @sitloongs
Thank you both for your replies
The explanation of the 1:1 NAT to the NVR and that is passes all ports to the NVR is very clear and I have done that as seen in the pics
The second part of the question I have been confusing you all, sorry about that. Let me try asking a simpler way because it has nothing to do with the 1:1 NAT part.
I want to have ALL devices behind a Peplink LAN port(switch connected to it) go out a specific public IP
I want to create another VLAN and assign that to another port on the Peplink for this
Under the LAN settings, you can create the VLAN.
For the port settings, I’m assuming you need to connect to another switch, you can set that in “port settings”
You can configure as “Access” port if the switch is dummy switch or switch running without VLAN VLAN trunk.
Not sure this is what you are asking 
@Saulius_Saltmeris
@sitloongs Yes that’s exactly what I was asking THANKS… last question I only use SMART or MANAGED switches capable of VLAN configs. How does that change things?
Also the NVR is working perfectly for the customer THANKS VERY MUCH
@Saulius_Saltmeris @sitloongs Hi I was just wondering if you missed my last reply and question or just busy
Hi James,
Could you explain your last question in more detail? I’m not quite sure what you are looking for related to the switches.
I called James last Friday and we got this solved. @james4 please send Frontier another ticket if you run into more issues.
