Different gateways for different computers

[NFKhalaychidi]

I have a device with OPNSense with 3 ports, one is for LAN, other two are for WAN1 and WAN2 from different providers
I have to do the following:
(1) All clients are using WAN1 to go to the Internet
(2) Some IP's have to use WAN2 instead
By default all clients are using WAN1 and (1) is working
How can I configure OPNsense to make (2) working?
I tried to configure the following firewall rule:

Code Select Expand

Interface: LAN
Direction: in
Protocol: any
Source: Single host 10.0.0.7/16
Destination: any
Gateway: WAN2_Gateway

When I enable this rule ALL computers are using WAN2, and nobody uses WAN1.
Any suggestions to fix it?

10.0.0.7/32

maybe?

Create a firewall ALIAS. Put those IPs for WAN2 in the ALIAS and use a firewall rule to forward that ALIAS to WAN2.

Yes. So simple. I thought "10.0.0.0/16" is subnet, and "10.0.0.7/16" is single host, but OPNsense doesn't think so

It works too! Thanks for this way

That has nothing to do with opnsense, but with network subnet masks in general ;-)
