Hi

Can some one assit me here, I have three brand new RB750 and all have the same issue, I can not connect to the Port 1 via winbox or telnet, I can ping it fine. I connect my pc with a static ip of 192.168.1.20 and the MT router eth1 port is set to 192.168.1.60 and I can ping fine but cannot connect via telnet or winbox.

I can connect fine via ports 2-5

If I defualt the unit and get connect my PC to say port 3 I get dchp IP Address if 192.168.88.??? and can detect the RB750 fine with winbox and telnet, then I configure Port1 with 192.168.1.60/24 but can not connect to it from another PC on the same LAN
as Eth1

HELP Please.

Thanks in advance

Most input on ether1 is blocked by default on RB750. There are default firewall filter rules, that will accept pings, but will drop other services. you can try to disable them.

/ip firewall
        filter add chain=input action=accept protocol=icmp comment="default config
uration"
        filter add chain=input action=accept connection-state=established in-inter
face=ether1-gateway comment="default configuration"
        filter add chain=input action=accept connection-state=related in-interface
=ether1-gateway comment="default configuration"
        filter add chain=input action=drop in-interface=ether1-gateway comment="de
fault configuration"

Thankyou for your help, all is working fine now,

I had to remove this one to get it to work though ?

filter add chain=input action=drop in-interface=ether1-gateway comment=“de
fault configuration”

Yes, the other rule

filter add chain=input action=accept protocol=icmp comment="default config
uration"

accepts ICMP packets. This is why you could ping the interface.

Lads how do ye remove that rule if you have ssh’d in from another box connected to the rb750?
I have exactly the same problem and this is the only way I can log in without driving to the site.
