esp8266: Allow forwarding between AP and STA interfaces

enhancementport-esp8266

I oppened a question some days ago about it and have not found anything anywhere https://stackoverflow.com/questions/44781305/micropython-nat-between-interfaces-on-esp8266
turns out that I can connect to a hotspot and act as a hotspot at the same time, but forwarding among interfaces is not permitted. I've being redirected to other software like NodeMCU but I would really like to use Micropython (and not having to compile ti myself)

esp8266: add note in docs about simultaneous use of STA_IF and AP_IF

not knowing about the issues of AP_IF when STA_IF is scanning was failing a demonstration... let's save other people from embarrassment ;-)

Assessment

Q Qwen · high

The query (issue #3177) requests a feature to enable IP forwarding/NAT between AP and STA interfaces on ESP8266. The candidate (PR #2613) is a documentation update that warns about performance limitations when using both interfaces simultaneously (specifically that STA_IF scanning degrades AP_IF performance). While both items concern the same component (esp8266/network) and the same topic (simultaneous use of STA_IF and AP_IF), the PR does not implement the requested forwarding feature. Instead, it documents a hardware limitation. The PR addresses the user's concern about using both interfaces but does not resolve the core request for NAT/forwarding capability.

Suggested action

Keep both items open. The PR provides useful context about limitations but does not implement the requested feature. The issue should remain open as a feature request, potentially referencing the PR to inform users about known limitations.
