Hello Rick, I am back on this problem. So to clarify:
- The modem/router is on 192.168.1.1 and has 4 Ethernet ports
- one port is connected to Balance one, which is configured to PPPoE the modem. In turn it will get a public IP address
- While the above is running, once another device will be plugged to one of the remaining Ethernet modem’s ports, it will get a private IP from the modem’s DCHP server. Access to the web interface will be possible.
Conclusion: a device connected to the modem might “dial up” PPPoE and get a public address, but once done, traffic to modem’s web interface will be denied, although a BalanceOne rule will attempt diverting traffic to the modem private LAN segment to the PPPoe WAN .
I guess this is by design. From a modem perspective, this is done to protect (NAT+firewall) any access to the modem’s private LAN
