I installed RH 6.2 with two 3c509s connected to a Cisco 677 which
goes to Frontier Communications. The other goes to my LAN. From the
MASQ machine I can ping both NICs, a client machine on the LAN, and the
router/modem. This is good. However, from the client machine I can
ping both NICs in the MASQ box, but not the router. Netscape works on
the MASQ box, but not on the client on the LAN. I am supposing MASQ is
working as I can ping the external NIC, but any ideas why I can't get to
the router. I think it is on the same network as the ethernet card and
the ethernet card is the default gateway. Any ideas?
