Very strange problem, can't ping specific client

RouterOS Beginner Basics
1

I tried to ping 192.168.88.10(Radius server) using my attached 2 configuration file from my RB951G (192.168.88.1), it’s very strange with failure for “Ping Not OK”, I did not find the root cause and it’s look like very simple configuration and I did it in before many times.

I’m sure the problem come from RB951G, because of I try to restore “Ping OK”, and it’s working and nothing change in my Radius server(192.168.88.10)

when I disable Hotspot, the Ping is working, so I think seems problem come from Hotspot, but I tried to compare 2 configuration file carefully, didn’t find reason.

Hope you can help me, this problem drive me to mad at recently.

Thank you, sincerely

At the Radius server you have static address or use dhcp ?

I know I can add 192.168.88.10 to IP-Binding list, then it’s working, But I’m interested in why can’t at before?

The 192.168.88.10 is the static address.

For hotspot it’s a normal behavior, you cannot ping your IPS given by the HOTSPOT … Yes you can add IP wtih IP Bindings …
And actually I dont sure what it is right way …
I dont have at this moment device for testing that, but try in DHCP server change “Bootp Support: from static to dynamic”

Dear Kickoleg, could you please help to check my configuration file? one of the configuration file is working fine and support ping without add IP-Bindings, but I don’t know what’s differences.

I tried to change DHCP as you said, but still can’t ping to 192.168.88.10. It’s so strange. I want to know the root cause.

Thanks for your reply.
