Yeah, incorrect firewall rules are a HUGE problem at super large companies that aren't doing infra-as-code at scale yet.
Sysadmins/server engineering/DevOps/SRE, Networks, and Security are usually hard silos at big companies.
"DevOps" gets a request from an app team to open a port between subnet A and subnet B.
DevOps asks Networks to do it. Security needs to approve it before Networks can do it (usually). A cohort of VPs somewhere need to approve it if those subnets are "production" (i.e. subject to serious fines if the data therein fails audit).
Networks outsources the request to their global services team in India/Phillippines/China/Brazil since it's literally a single command, but they are done in bulk. These changes are only done afterhours, partly because of outsourcing latency, partly because of regulations.
The firewall person types in the wrong port. Emergency change request gets filed to fix. Fixed in 1-3 days after the CTO/CIO and some SVPs approve it (and maybe yells at people for wasting their time).
The requester asks for the wrong port. Too bad, so sad, you're waiting another week.
The app team asked for the wrong port. Same outcome as the DevOps person.
