UPnp working at double NAT but not in bridge mode !
Posted: Fri Jul 05, 2019 4:42 pm
I used to connect my modem and Router in double NAT (with DMZ enabled at the modem) and Gargoyle router upnp worked with no problem at the past .
But for my new TP-WR1043 V2.1 it didn't work with gargoyle 1.11.0 , searched and found that there is no workaround for now , so reverted to gargoyle 1.10.0 and again its working as it should in Double NAT with DMZ enabled at modem , i can see the forwarded ports with no problem at router .
Wanted to try the modem bridge mode with PPPOE enabled at Gargoyle router and I could connect to internet but just after manually changing the modem IP at modemaccess.sh , and for my surprise the upnp didn't work only **** *********** **** and no ports are shown !
When enabled DMZ at gargoyle for my PC's ip the port forward process is working again at PC (always using gameranger to test) so the modem is not the problem and the Ports are indeed forwarded from modem to router but not to the PC using the upnp , its something related to (Bridge mode + PPPOE ) connection type only , as its already working at double NAT with DMZ .
A note : DHCP is disabled at modem and enabled DMZ option for router ip at the modem (disabling it not making any difference)
