Non riesco a capire se sia un problema del router o del firewall.
Considerando che:
- la stessa richiesta "Cisco 857->server con apf" tramite LAN funziona benissimo
- la stessa richiesta "altro router->server con apf" tramite WAN funziona benissimo
- la stessa richiesta "Cisco 857/altro server senza apf" tramite WAN/LAN funziona benissimo
Credo dipenda da qualche impostazione del router ma non sono più dove mettere le mani.
Avete idea di quale possa essere il problema?
