Many-to-one NAT on same port /app?

SThatipelly — Wed, 18 Mar 2020 19:53:18 GMT

I have 4 public IP addresses that are needed to NAT to a one single private IP server in DMZ. They all listen on same port and same application. Anyway I can get this done without greatly impacting users?

Thanks.

Hello,

This would just take 4 NAT policies along with security policies.

a.a.a.a -> nat to -> i.i.i.i

b.b.b.b -> nat to -> i.i.i.i

c.c.c.c -> nat to -> i.i.i.i

d.d.d.d -> nat to -> i.i.i.i

Regards,

@OtakarKlier thanks. I thought of the same solution but wanted to get an opinion before bringing into prod.
