PAT with CGN NAT

Ammar_Taha · September 2021

hello

i have A10 AX1030 on 4.1.4, build 332 and i configure CGN NAT on it my question is can i make some of my private IPs go over one of this CGN NAT pool

let say i have public start IP x.x.x.3 end address x.x.x.254

is there any way to use x.x.x.200 for another private range

Hi Ammar.

The easy way is use Fixed-Nat, this reserves a number of ports (1000 in this case) in the public ip pool for the internal clients, this is an example, please use the reference document in the portal for more info:

ip-list external-CGNAT-range

65.64.66.3 to 65.64.66.254

ip-list internal-CGNAT-range

172.24.16.200 to 172.24.16.254

cgnv6 fixed-nat inside ip-list internal-CGNAT-range nat ip-list external-CGNAT-range method use-least-nat-ips offset 0 ports-per-user 1000 respond-to-user-mac
