Hi Bryan, glad you like the software! Regarding the error - how is the e-smith server configured? Are you using DHCP on the external interface? Are you sure the DHCP server is responding correctly? Do you know anything about the machine 10.79.16.24? It's hard to tell from this report, but it looks like the e-smith server is reporting a warning, that a machine with the IP address 10.79.16.24 is generating unexpected ICMP errors. Apart from this error, is the e-smith server and gateway working correctly?
