Connectivity issues with pppoe
I have the following topology – Firewall (huawei USG6300), connected to AC (AC6005) and multiple APs. The WAN port of the firewall is a pppoe connection with a dialer interface. I can ping any address from the firewall, but no ping gets out from the AC (AC can only ping the firewall and and the Aps. I have no experience in the pppoe configuration, it was configures by a collegue before me. The last resort gateway of the firewall is the dialer interface. I can post the interface, routing tables and nat settings of the devices. I don`t know if the problem is with the pppoe or the communication between the ac and firewall.
Any advice is appreciated.
