don't have ping but see the IP on scan?

RouterOS General
1

Hello ,
maybe someone here can help -

I have a router with a computer connected to it using IP 10.0.0.120
when I try to run a ping from the router terminal I get no replay
but when I run Tools–>IP Scan - 10.0.0.0/24 interface = ethernet
I can see the the replay and the MAC.

what can cause this problem ?
and how can I fix this?

Thanks ,

It is possible that ICMP protocol is blocked, in that case ping will not work.

I have check and connected the copmuter to my computer and run the ping command
I got a resualt
so it’s not this

I also thought that for some reason the ping is block so
I have try to connect using RDP (NAT to 3389 ) - didn’t work
and it did work before(I was able to connect to the remote computer )

IP scan does firstly ARP requests which are usually not blocked because that would deny a bit whole purpose of the network.
I am sure if you do ARP ping, it will get replies as well, while normal ping won’t.

Personally, I am pretty confident this is usual Windows firewall issue - When you connected your router, your computer asked you whether the network is private (safe = ports opened) or public (unsafe = ports closed). Based on that, Windows sets the firewall and actually remembers the setting. Due to that, it may present different behavior when you connect it to different networks.
You can always adjust it in your network settings on the computer.

yes when I run from the tools
ping - Arp Ping
I get a repaly from and see the MAC
so why can’t I reach to the device

my mistake it’s a PI with VNC on it and the port is tcp 5900

when I connect the PI to my computer and open VNC to 10.0.0.100 port 5900 it’s working

Very strange

what can it be ?

Thanks ,
