Ping problem solved by issuing command "netsh firewall set icmpsetting 8 enable"

I have two Broadband-Hamnet nodes, KV4I-100 and KV4I-200. Both are running version BBHN 1.0.0. Both are configured as 5 host direct Mesh Nodes and each has one PC wired to the LAN port. Each PC can access the Mesh node status screen on both KV4I-100 and KV4I-200.

KV4I-200 is connected to Whitebox2 which is running a server application (DRATS) on port 9000. Whitebox2 is assigned a DHCP reservation. So is Whitebox1.

The DRATS client running on Whitebox2 connects to the server app on Whitebox2 via whitebox2:9000.

KV4I-100 is connected to Whitebox1 and Whitebox1 is assigned a DHCP reservation.

The DRATS client running on Whitebox1 connects to the server app on Whitebox2 via whitebox2:9000.

Both computers can communicate via the DRATS application but neither computer can ping the other.

Attempts to ping by IPv4 or IPv6 local-link addresses also fail. (Ipconfig reports only an IPv4 and an IPv6 Local-link address.) However, when pinging by name, the system does recognize the domain as "local.mesh" and reports the correct IPv4 address.

Examining the network adapter properties reveals that the adapter is set for DHCP and has the correct IPv4 DHCP server, DNS Server and Gateway addresses but the entries for the IPv6 DHCP server, DNS Server and Gateway addresses are blank.

I'm also unable to connect from Whitebox 2 to a webserver running on Whitebox1 but I'm hoping that problem will clear once I can ping.

Any ideas on how to enable pinging and hopefully web server access?

Thank you,
