Allow Proxy Arp to Bind to CARP Interface

Description
Hi,
We are using a cluster pfSense to NAT 1:1 two network.
I need to make Proxy ARP VIP to bind to CARP Interface.
Now, it is not allowed.
Is it possible to make it work ?
What is important (for me) is to "expand" a full network with a single line of configuration
I also try with "Other" VIP, but same message.
- Status changed from New to Rejected
no need. IP alias or more CARP.
Ip Alias can't expand a whole network withing a single line of conf
When configuring a Proxy ARP you can specify a CIDR directly (a range of address ie 192.168.0.0/24 will be equivalent to 255 ip addresses)
With IP Alias or CARP we can only specify one address at a time.
Am I wrong ?
IP Alias VIPs don't work that way, but proxy ARP VIPs are not and cannot be compatible in the way you describe.
On 2.1, "Other" type VIPs can work with a subnet mask to expand to an entire segment, but the subnet must be routed to you, it can't be your WAN subnet.
If the IPs in question are in an interface subnet, there is no way to do that properly for failover with "a single line of config". If the subnet is routed to you, use 2.1 and "Other" type VIPs. Either way, the original request as stated isn't possible.
Thanks a lot for your time and sorry for the useless ticket opening.
