Is there any way to easily disable ping replies on the WAN interface? We are running into an issue where a couple of our routers are being ddos’d and causing data overage.
I am hoping its just a simple checkbox somewhere, and I am just missing it.
Hi and welcome to Digi Forum!
In order to block ping or other unwanted traffic, you should use the firewall, see the User Guide section here:
Also, I would suggest you to look at this guide as well: https://ftp1.digi.com/support/documentation/AN_018_TransPort_Security_Lockdown.pdf
I hope this helps, if you need any further assistance please send us an email to tech.support@digi.com.

I tried “block return-icmp unreach in break end on ppp 1”
However, it appears to have blocked all traffic, instead of just ICMP. The unit is now not accessible.
Is there a simple firewall command that blocks only ICMP ping requests from the PPP 1 interface?
