Hi team,

I'm using Static Outbound IPs on my backend service (project: Tensortick-Backend, service: tensortick-backend, production environment, domain api.tensortic.com).

I currently have 3 static outbound IPs assigned:

152.55.180.240

162.220.234.242

152.55.180.241

I'm integrating with a broker API (ProStocks) that requires IP whitelisting, and they can only whitelist a maximum of 2 IPs on their end — they've approved 152.55.180.240 and 162.220.234.242, but will not add the third.

Since traffic is load-balanced randomly across all 3 of my assigned IPs, my login requests to this broker fail whenever the 3rd (unapproved) IP is used — which is roughly 1 in 3 attempts.

Is there any way you can either:

Restrict my service's outbound traffic to only use 2 of my 3 assigned IPs, or

Reassign my static IPs to a smaller pool of exactly 2, or

Suggest another approach on your platform to guarantee outbound requests only ever use a fixed, small set of IPs?

This is blocking a production integration for me. Happy to provide any further account details needed.

Thanks!
