Long time nerd/networker, but first time MikroTik user here!
So, i bought a CRS125-24G-1S-RM given that it seemed to represent a very good value for money.
It does, however, scare the crap out of me from a feature perspective given then price.
Anyhow, I have got it pretty basic now. ether1-gateway to my fiber connection, and local access on the rest of the ports.
I have added some dstnat, set up uPnP/SNTP, found and modified a NO-IPscript and general housekeeping
Now, i need to get creative, and I cannot get the "Eureka!" moment to figure it out.
From my fiber i have one CAT5e to my patch closet. Now i need to hook up the providers Zyxel-box to get VoIP working.
So, i would need to set up a VLAN (i guess) to sort this out. I know i could definit a three port block for this, and then run one cable to the fiber, one to the zyxel, and one to ether1-gateway.
But, surely there must be a way to bridge ether1-gateway and another port and hook my zyxel there? Or some other cleverness.
Yes, the provider gives me several public IP's so that is covered
In the attached file, the "top half" is the function that I desire, and the "bottom half" is how I would like to wire it.
