Model: Archer C64
Hardware Version: V1
Firmware Version: 1.5.8 Build 210609 Rel.60832n (5255)
Dear please help
Need Port Forwarding
External Port : 49152-65534
Internal Port: empty ( need forwarding same external port to internal port )
in old device for this function need use Internal Port: empty
but in Archer C64 Problem
if
External Port : 49152-65534
Internal Port: empty
write " not allow to be empty "
if
External Port : 49152-65534
Internal Port: 49152-65534
write " Invalid format "
why write forwarding similar old function
External Port : 49152-65534
Internal Port: empty ( forwarding same external port to internal port )
