TP-Link ER8411 Dropping Packets

2 weeks ago - last edited 2 weeks ago

Tags: #Load Balancing

Model: ER8411

Hardware Version: V1

Firmware Version: 1.1.0

So here's is the Topology, basically ER8411 is being utilized as a Load Balancer and not as a Router.

The issue is that every 5 minutes a packet or two is getting dropped. I've pinpointed that it was the ER8411 that was causing the problem because I've tried pinging the gateway, Mikrotik, and individually checked all ISP. But when I connected to the ER8411 that's when I get packet drops.

ISP 1,2,3 is our Primary WAN and 4,5,6 as Backup so we are mostly just using the 1,2, and 3. Turned on the Load Balancing feauture, "Enable Bandwidth Based Balance Routing on port(s):" feauture on all ports, WAN, LAN Settings, and that's pretty much it. Almost a plug and play set up.

Hope anyone out there could help, thank you so much!

Hi @pines_2600

Thanks for posting in our business forum.

Something you should know.

As you have enabled the load balancing, you are likely to be balanced several times when a connection is initiated. Due to you creating a double-NAT in this situation, the router basically cannot identify the connection source.

I think this is expected behavior. Or you should consider removing the double-NAT in this case.

Setting the 1 WAN as the primary would definitely create a stable link, is that true? If so, that's not a problem with either the ISP line or the router itself.

And note that certain web like banking, are sensitive to your IP address changes. If this is your case, we do not have ways to resolve it. Consider fixing the line if you use certain apps and webs that are sensitive to this.

We also do not have any recommendations for such a scenario. Our router is usually used as the primary router. There is no mode for only load balancing.
