AWS outposts documentation change

Service: outposts · 2026-04-04 · Documentation low

File: outposts/latest/userguide/private-connectivity.md

Summary

Updated security group configuration instructions to specify required inbound traffic rules (ICMP, TCP 443, UDP 443) and added a note about both TCP and UDP being required for private connectivity.

Security assessment

This change is identical to the one in the network-userguide version, providing consistent security configuration documentation across guides. No evidence of addressing a specific security issue; appears to be documentation improvement.
