I'm moving my server from DigitalOcean to a local cloud host. On DO, I have inbound ICMP disabled to prevent a DDOS attack - because DO has transfer limits, enough network traffic will knock a prepaid server offline or incur high charges against a postpaid server.
My new host doesn't have a transfer limit, but they're refusing to disable inbound ICMP. I can't understand why since I see no downside, and it seems suspicious to me. Is there any good justification to allowing inbound ICMP?
