NAT 1:1 with internal ip in an alias ?

[patrick38]

Hi,

I have about 30 ips on one wan connection
I want to put a network range of the lan for each ip

Example :
192.168.1.1 => 1.20 => IP1
192.168.1.21 => 1.23 => IP2
192.168.1.24 = 1.62 => IP3
…

For the moment i find how to add a virtual ip to a host with NAT 1:1
I see it's also possible to make it with network

But is there a way to do it with an alias ? or an ip range ?

I hope that if someone whant to put 1.1, 1.72, 1.128 and 1.203 on one virtual ip he doesn't have to do a rule for each ip ?

If it's not possible, maybe a random between all virtuals ips could be enough for my case, but ideally network range or alias would be better
Thanks
