887va - allow remote ping

[John Adams]

Hi,

Is there a way to allow only certain IPs to be able to ping my 887va remotely over the internet to check it is up and working? This is so my offices can confirm it is up.

Thank you.

If you have a static address, you should be able to create an acl that allows only those certain addresses:

ip access-list ext Inbound

permit icmp host host echo

You would apply this to your wan interface inbound. There's an implicit deny all at the end of the acl, so you would need other entries to allow for web traffic, ftp, etc, if you're hosting servers on the inside. Otherwise, if you already have an acl, just add the above line to it.

HTH,
John
