Port forwarding issue in 5268AC
After reading all of the recent comments related to port forwarding issue on this appliance(5268AC), I still don’t seem to understand if there is any solution. Can someone clarify if there is any way to make the ‘pinhole’ concept work to avoid using the DMZ/Bridge to personal router as workaround? I am trying to simply forward TCP/UDP traffic on ports 80 and 443 to a wired port that my Ubuntu 16.04 server is connected to but have not been able to accomplish it in past 4 days of trying. This rudimentary configuration has been working in my previous provider’s network with my own router attached to their modem.
I verified that putting 5268AC in DMZ mode works both when is directly connected to my server and when my router is hooked but I experience degradation of service in later case which I want to avoid. Using pinhole forwarding in firewall rules won't allow any packtes get into my server side. I tried both standard application HTTP/HTTPS and user defined one with no success. I alos played with advanced setting Firewall advanced configurationStealth Mode, Block Ping Strict UDP Session Control with no luck.
I am looking for a clear answer if the pinhole concept works in this modem and if it does what am I missing (ie.e firmware upgrade or sw/hw upgrade). If it doesn't can anyone recommend a router that is delivers good perfromance on Gigabit net.
Here is my device information:
Manufacturer Pace Plc Model 5268AC
Hardware Version 260-2173300
Software Version 10.5.3.527283-att
Thank you in advance.
