Packets loss when adding switch

Hi guys,

I’m having this one setup where a mikrotik is infront of this one Ubiquiti Powerbeam connected to another on a tower with a switch and this switch is patched into more switches (around 30). The issue now is when theres an additional switch patched to this packets are being lost.

This all is going over NAT, sadly I dont have public IP’s, what is the best way to go around this? Using VLANS? Would I need to place a router at the tower? Create routes?

Let me know!

Ian
