Back to a CHR?

Friday 13th was an exciting one in my household! Not only did I kill the internet for everyone for a good 3 hour period whilst I swapped from an Ikea Lack table to a “real” 6U cabinet causing huge disruption when my planned single patch panel turned into 3! I also fired up old faithful and stuck on a fresh copy of the latest (6.42.6) CHR into my VM box.

Now I have my spare ESXi box housed in the attic in a real rack it means I don’t need it screaming away in the cave so I can finally move back to a CHR build and keep it. My rough maths says the CHR unit will have around 4-5 times the performance of the RB3011 which will now get moved to the cave as a dedicated VLAN breakout switch (or maybe sold) but ultimately I can employ some far more complex queues without worrying that I’m running the CPU up too far.

My long term plan is to SFQ my LAN traffic but then pick out particular traffic types from that and SFQ them against each other whilst doing some PFIFO pulling them all together. I’ll try to document as much as I can but in short it will be a huge amount of packet marking so CPU grunt is needed. I’m even now tempted to look at upgrading the CPU so it’s more than a dual core!

Fun times ahead.

MikroTik Hairpin NAT With Dynamic WAN IP Tutorial Update

I’ve had my YouTube video out there for a while now (link) and whilst it does get a fair amount of traffic I have always wanted to follow it up with something written as well.

I’ve now just added in a full written tutorial of how to achieve this by using my easy to use drag and drop .rsc file. Head over to the MikroTik section to see more or for a direct link go here
