Title: EG105G-V3 port mapping with two WAN lines
Hello,I have this router installed with two WAN lines, throught two LTE routers. It configured to receive DHCP. The problem is that the EG105 can´t perform port mapping because the IPs it detects throught the WAN ports are local. The configured DDNS service correctly detects the public IP. I think the problem is that I can´t put the LTE routers in bridge mode, but I'm not entirely sure. Any idea ?.
Regards.

Dear Sir,

Thank you again for your inquiry.
I would like to confirm again that the EG obtains the intranet address under the LTE router and is not directly connected to the ISP network, right? And then we hope to do port mapping on EG, right?

I wish you a happy life!
Best regards,
Eric

Dear Sir,

Thank you again for your inquiry.

The problem is solved, I have replaced the LTE routers(RG-EW300T) , with others (DLINK DWR921) that would allow me to configure them in bride-ethernet mode. Now successfully performs DDNS resolution and port mapping.
Best regards
