Summary

  • Adds a <Warning> callout in the Egress tab of the Networking section on the Run a Node page
  • Informs operators using network ACLs (as opposed to stateful security groups like AWS SGs) that they must also allow outbound traffic on ephemeral ports 32768–60999 (TCP/UDP)
  • Explains why: ACLs are stateless, so without this rule, return traffic from peers is silently dropped

Context

Based on internal discussion with Francis Li — the existing port table covers the well-known ports but omits the ephemeral range, which bites operators who use ACL-based egress control instead of stateful SGs.

Add a Warning callout in the Egress tab explaining that operators using
network ACLs (not stateful SGs) must open outbound ephemeral ports
32768–60999 to avoid response packets being silently dropped.

Keep master's cleaner prose ("superset of ERC-20") over the branch version.
