@ -5,6 +5,12 @@ Interface configuration
All traffic in OPNsense travels via interfaces. By default, WAN and LAN are assigned, but many more are possible, like
GUESTNET (:doc:`captive portal </manual/captiveportal>`) and PFSYNC (:doc:`high availability </manual/hacarp>`).
.. Note::
For legacy compatibility WAN interfaces set to type DHCP or interfaces with an *Upstream Gateway*
send reply packets to the corresponding gateway directly, also when the sender is on the same interface.
This will break connectivity in some rare scenarios and can be disabled via
**Firewall->Settings->Advanced->Disable reply-to**.
