Hi,
I am unable to access the device via IP address.
This has happened suddenly.
Although when trying via Winbox I can access the device with MAC address but even Winbox cannot access the device when trying via IP.
What could be the reason??
Do you connect to the device directly, maybe somebody else having the same IP, so if you check the arp with the computer to check if the mac address of the ip is the Mikrotik device.
This is example is made with WIndows command prompt.
C:\> arp -a
Interface: 192.168.1.4 --- 0xd
Internet Address Physical Address Type
192.168.1.1 a0-21-b7-b0-da-2f dynamic
192.168.1.255 ff-ff-ff-ff-ff-ff static
And if you are on Linux, the new arp checking tool is ip.
[patrik@archlinux ~]$ ip neighbour
192.168.0.26 dev eth0 lladdr 12:23:45:13:a4:07 STALE
192.168.0.1 dev eth0 lladdr bb:ee:12:12:c2:90 REACHABLE
No I have just 3 machines on LAN
Also if conflict it would have been flagged!
If you are so sure to rule out IP conflicts:
in my experience it's usually an indication of an error in some IP settings on the device ... (duplicate IP also falls under that category)
Technically it is the internet gateway device and everything is working just fine except accessing this gateway device over IP address.
Post your configuration or check the settings mentioned here (first code snippet):
You could have the interface you are connected to not categorized correctly as LAN or have some modified firewall rule that prevents connection (in chain=input).
No. Nothing changed... It was accessible over IP and then now suddenly this issue!
