Load Balance Incoming Connection Issues - Similar IPs - Connect from Home to Work.

RouterOS General
1

Hi Guys, I have a 450G setup at work handling 2 internet connections setup in a load balance situation.

ISP1 is 180.181.97.xxx
ISP2 is 203.206.223.xxx

Now I just changed my home internet to same as ISP 1 and my home ip is now

180.181.102.xxx

I assume they are using the same subnet or something

I can’t connect to work on ISP/ISP2 at all on any ports etc. (I use RDP and FTP)

If i disable the ISP1 at work, I can connect flawlessly from home.

What configuration can I add to fix this situation?

You do not have proper mangling on WAN->Router and WAN->LAN connections.
A connection initiated on a certain ISP MUST BE replied to using the same ISP.

Go over this presentation, it will explain more:

I changed my setup based on your guide but having a slight issue with the traffic monitor working. I’ve added you on skype if you don’t mind chatting for a few mins :slight_smile:
