WHS Server - No Internet Connection

Question
-
Originally posted in the Software Forum, but this appears more appropriate...Despite what I naively believe to be diligent efforts, I've been unable to identify the reason that my WHS server no longer can access the internet. (Unfortunately, I can't associate the problem with any particular system/configuration change as it went unnoticed for many months.) Just to be clear - I'm talking about basic internet access to receive WHS and antivirus updates - I am NOT trying to configure remote access or a network home page as my ISP precludes server use (sigh).
Background:
Wired & wireless home network with apparent good connectivity across network.
Backups and RDP from all clients to Server work fine...
Other network clients all have full internet access.
Server IP (192.168.1.254) is DHCP assigned via a static reservation in the Verizon router. (I've also experimented with a static address on the Server side with the same non-results.) Current IPCONFIG/ALL results for my Server are reproduced below: (bolding added)Windows IP Configuration [Server]

When attempting to ping internet addresses, however, it appears to resolve the IP properly but times out (on the return path?). See results of Server ping to www.google.com below:

Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),NSLookup confirms that the DNS (via the router IP) is resolving properly. Thus, the problem acts like a router or firewall inbound configuration issue but the other clients successfully use the same router IP (192.168.1.1) as the Gateway and DNS Server without any trouble (see Sample Client ipconfig/all below)

I'm pulling my hair out over this as I'm sure it's something really stupid on my part... Any ideas or additional troubleshooting suggestions would be greatly appreciated.

This is now resolved - although it's still not clear EXACTLY what was preventing the Server internet connection, removal of the static IP reservation in the Router DHCP permitted the connection. Now I'm just specifying a static IP on the Server itself and all is well...
