In the Security > IP Source Guard tab of the RV340 (fw 1.0.01.17) selecting 'sort' either up or down does not work to sequence IPv4 Addresses.
That's also true for the DHCP Binding table sort for IPv4 Addresses under Status-and-Stats > DHCP-Bindings
MAC sorting works fine in both cases--just not the IP address field.
