Noob question about port switching

Hello,

Last week got my new FTTH broadband at home and the router provided by my ISP is just too locked and can’t configure some useful thing i like to static ARP to Wake on Lan or some others… so i decided to get a Mikrotik 951G-2HnD.

I need to connect my Mikrotik simultaneosly as my ISP router (because the ISP routers gots the phone configuration and it has 2 POTS RJ11 ports to inject the phone to my old telephone installation (analog phones).

The problem is that I dont want to put another switch on my table to connect both devices to the ONT so i though i could use some of my Mikrotik router as switch something like this (imagine 1 port as WAN, 1 port as LAN and 3 ports switched):

Connect the ONT to one switched port on the Mikrotik, connect another switched port to Mikrotik itself (to the port configured as WAN) and another switched port to my ISP router WAN interface.


COuld it work? Or will the Mikrotik go crazy because of a wire connecting to itself even if one is a switched port and the other the WAN port.


Thanks you, and excuse my English :slight_smile:

The 951G-2HnD has a built in switch with ports 2-5 already bridged as the default.

You should never need to connect a device to itself…

Im wondering if this sceneario could be posible and how to set it up… not getting comfortable with winbox and all that options…

  • Port1: Connect the ONT on it. To communicate with the ONT I must set a VLAN 1074 and DHCP to get a public IP address.
    -Port 2 : Connect my ISP Router. I want it to get also DHCP IP from the ONT, i can set the VLAN on it if needed or use the VLAN already set for Port1.
    -Ports 3,4,5, WLAN: LAN ports, here i should be able to connect my PC’s through ethernet and also wireless, the local DHCP server with work on this port using NAT. I will have 2 or 3 NAT rules for remote desktop, wake on lan…maybe some P2P.


    Is this setup posible? how?

Thats possible… but does your ISP allow you to get two IPs?
