Stop the presses -- I solved the problem!!!!
(1) I needed to have connectivity between the router and my LAN. So I connected the E0 interface to the Cable-Modem Router (10/100). (2) Then I configured the E0 interface to be on the same subnet as my LAN. And much to my "aged" amazement (and relief!) -- it worked. BTW -- one can ping in hyperterminal -- from the router to the PCs on the LAN. Cork>ping 192.168.1.101 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.1.101, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms Cork>ping 192.168.1.103 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.1.103, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms Cork> Lastly, thanks for your offers of assistance. I do feel a bit stupid in bothering everyone. But it's been a few months since I fired up these routers and I overlooked some basics!! Oh well . . . . Thanks again -- and I owe you one.
