My zoom x6 modem doesn't block pings (ICMP). How do I configure?
Blocking ICMP pings on a Zoom requires a few steps:
1) Go to Advanced Setup and select Advanced Firewall Filter.
2) Enable Advanced Firewall Filter.
3) Click on Security Policy Configuration.
4) Click on Policy Rules for "Add Firewall External-Internal Filter Rules."
5) Click on Add Policy Rule.
6) In the row labeled "Protocol," select "neq" and enter ICMP where it says "(Protocol Number or Name)."
7) In the row labeled "Select the direction to filter packets," select BOTH.
8) In the row labeled "Filter Action," select DENY.
9) Click on Save Changes and repeat 1) through 5).
10) In the row labeled "Protocol," select "eq" and "TCP." Below, select BOTH for direction, and ALLOW for filter action.
11) Save changes and repeat 1) through 5).
12) In the row labeled "Protocol," select "eq" and "UDP." Below, select BOTH for direction, and ALLOW for filter action.
13) Save changes.
14) Go back to Basic Setup and save changes to Flash.
That's it. Good luck!
