Double NAT problem on ER 605 with double LTE WANs connected
Hi there,
I use ER605 to aggregate bandwidth of 2 LTE connections bandwidth. I made a very basic configruation, with dynamic IP on both WAN, and load balancing enabled (with application optimization and bandwidth based balance routing both disabled). All the rest of the settings are as set out of the box.
Bandwidth aggregation works.
However, there as some sites that require to log in that do not work properly (log in not possible) when both WANs are up. When one of the WAN is down those troubled sites start to work and log in is possible without any issue. I was adivised that it might be related to double NAT problem.
How shall I configure my ER605 and/or other network elements to make it work without errors described above?
My network setup is the following:
- 2 LTE modems / routers connected to ER605 WAN inputs
- ER605 LAN output connected to tp-link deco M9 mesh router
Thank you
