whitelist ip address - local machine

I am running a load test from my local machine around 90,000 rps.

get request; the token expires in 15mins
simulation:

setUp(bridgeBarApiGetUserDetails.inject(
  rampUsersPerSec(1) to 100 during (60 seconds),
  constantUsersPerSec(100) during (820 seconds)
).protocols(httpProtocolConfig))

I am wondering how Gatling uses an IP address?

Our load balancer is rate-limiting and sending 403. I want to avoid that so how can I use my local IP and whitelist my IP it does not rate limit.

Thanks
Akshay

I was able to fix by whitelisting my IP in a load balancer.
