Load balancing 4 WANS with 2 cascading routers - probably NAT problem

2019-07-30 16:20:03 - last edited 2021-04-19 12:03:27

Model: TL-R600VPN

Hardware Version: V4

Firmware Version: 2019-something (latest)

Humbly asking for help with my crazy unprofessional setup...

I have 4 Raspberry Pis serving as a Wifi to Ethernet bridge with Pi-Hole as DNS server. The second layer is TP-link TL-R600 VPN router as Load balancer. The third layer is TP-Link's LAN connected to the second WAN of ASUS AC88U with NAT switched off on WAN.

The download speed increased, no problems there but I can't open (or takes much longer) every other webpage. I suspect it's a NAT problem, I tried setting up DMZ on TP-Link but it didnt change anything.

Please help with tuning this beast.

Thank you!

You can try to ping the webstie to check the latency.

Generally enable DMZ will not get the higher speed. It's used for open the port. If you doubt that multiple NAT cause the issue, you also can connect the PC the R600VPN directly and check the latency.
