Arris BGW210-700: Being blocked with "Disallowed WAN-side management service access"
The router is blocking an outside connection. The log shows the following message "Disallowed WAN-side management service access". The remote PC is trying to connect via port 443. I added first a NAT rule entry to open port 443 directing to an internal server. Since that did not fix the issue I set a DMZ using IP Passthrough to the internal server. I'm still being blocked. I've tried also turning off the firewall and all filters, but the issue remains. What I'm a missing? Any other router all I have to do is open port 443 and directed to an internal server.
