I am dissatisfied with how difficult a Ubiquiti Edgerouter (ER-X) is to administer.
The main thing I want is Gigabit routing with firewalls and NAT. Full IPv6 support and enterprise-grade management and debug are a must as well. The infuriating mix of GUI and command line plus not sticking to Cisco naming conventions for commands like Brocade did is maddening, and the lack of good debug options (GUI-based packet capture that doesn’t work) and good documentation for the ER-X is so annoying that it makes the $60 price point not worth it at all.
Rb750gr3 will not be able to pass gigabit thru under “normal” contions. It mostly depends on the rules complexity and other things you will set. If your rules allow to use fast track it will help a lot and I can imagine that you could get closer to the gigabit throughput.
We have installed MikroTik on very demanding scenarios: a customer with 1k+ wireless access points, ISPs providing service to any amount of subscribers, data centers with critical applications running, communicating 2 or more cities and supporting thousands of users, and so on.
If you are a Cisco guy and you decide to enter the MirkTik world, I think these 2 articles from one of our senior Network Architects will be useful
The various Mikrotik models all have the same interfaces. I always use Winbox which is a little windows utility used to configure the device. It’s very snappy, the device never needs rebooting. You can also connect by MAC address so you can change the IP of the device without having to reconnect.
It supports packet-capture in the pcap format, so you can open the capture files in Wireshark. Also, you can copy and send all packets passing through the router to your machine and you can view the capture in real time with wireshark. It has a tool called Torch which shows active connections and bandwidth being used. I use this often for troubleshooting.
The edge router’s interface has more graphs and colour, but I never like I’m missing out on any features or troubleshooting tools.
