RB1200 throughput issues

RouterOS Beginner Basics
1

We’re having a some extreme throughput issues here with a RB1200.

It is currently acting as a NAT within a private network. It also obviously assigning DHCP to this isolated network behind the NAT. This is to remain undiscoverable, but still obtain access to the resources in the other network. However, with the current setup we are only getting about 10Mb connections when going through the NAT where both sides are 1Gb connections. We are still unsure if this is related to the NAT or not, as all other communication appears unaffected.

There are problems with port 9 and 10 on RB1200. There are many posts on related to these 2 ports. Try to avoid to use these ports.

Disabled port 9 and 10, removed 8 and 9 from the bridge, and used port 8 instead. Did a quick test with SMB throughput and got about 50MB/s which is acceptable considering the environment.

This news is rather upsetting to me though, to find out that the device does not function as advertised, and will not work for what we had planned. That’s 20% of the device that is almost completely unusable due to this. Do you know of any other issues that we should be aware of? Are there other models that would fit our needs better? Or should we just try and return this thing for a full refund?

This is the only model that have this problem - if you take a RB1100hx2, no problem on any port.

I slammed into this head first several months ago as well. Same result. Kill ports 9 and 10. Things work great.
