Sorry I forgot to say that two LOCAL interfaces are setup for HOTSPOT modeThanks a lot for interest. The setup is very easy. We have one internet access (ADSL) w/ 6 valid IPs address connected to a switch. The two PCRouters are in the same switch, using "Public" interfaces, each one of them with proper IP address. Each PC router configured to serve two different “Local” networks .
ADSL>SWITCH>PCRouters (A and B)>Local A and B networks
What kind of traffic? Are you looking at an ARP or Broadcast storm between the two routers? Maybe you've got a device inside the network that's connected to both the A and B networks and you've got a loop that is causing problems.traffic is growing a lot when they are connected
