Hi there
I need to setup an additional site and I have the following requirements:
- The IP address range will be routed through a static IP address that will be assigned to the router with MAC reservation.
- Behind this static IP address, the subnet for the IP range is implemented by the customer (5 public IP addresses are available in this subnet).
I get a static range /29, (i.e. 55.66.77.88) whereas:
- .88 => the first address will be the network address
- .89 => the second address is the local gateway
- .90-94 => the 3rd to 7th address can be used as desired
- .95 => the last address is for broadcast
How do I need to setup opnSense to use this subnet with a private LAN subnet and NAT routing?
I guess the WAN is simply DHCP.
Do I need to add Virtual IPs fot the static subnet?
Thanks for your hints!
This already assumes that a subrange like /30 or /29 can be assigned using DHCP. Is that supported by DHCP in the first place ?

No, the subnet will not be assigned using DHCP. Only the IP address of the router will be assigned. This IP is not part of the subnet!
It is like this:
WAN / Internet
|
| Cable-Provider
|
.-----+-------.
| HFC Modem | (Bridge)
'-----+-------'
|
| WAN
|
.-----+------. <--- IP assigned by ISP/DHCP
| Router |
'-----+------'
|
| Public IP subnet (/29)
|
.-----+----.
| opnSense |
'-----+----'
I want to combine the router and the opnSense in one...
