Routing, WAN Ping and Double NAT
Hello, I built the network below using TP-LINK Business Solutions devices only. Everything behind the router ER7206 is my local private network that is further divided into subnetworks by ER605 routers. I am now struggling to achieve the following:
1) Ping WAN IP of ER605 routers. There is no "allow WAN ping" option.
2) Make the routers to route traffic from hosts behind one ER605 router to the hosts behind the other ER605 router. I am able to add the static routes but it seems the packets are discarded when their reach the WAN interface of the destination ER605 router.
3) Hosts behind ER605 routers are under double NAT. How to resolve it? How to disable NAT on ER605?
I am afraid answers to all 3 issues will be something like that it is not possible. So let me ask this - is my network design flawed? Am i asking for things that are really not supposed to work in a business solution? Are any of these points on your roadmap?
Best regards,
Radek Tyrala
