Here's the short version:
Netgear to SME 6.0 as server-only working great for email and DHCP. All of the sudden out of nowhere, no internet. But everything else worked. I could ping an address correctly but couldn't pull it up in a browser.
I turned off squid with:
/sbin/e-smith/config setprop squid status disabled
/sbin/e-smith/db configuration setprop squid Transparent no
/sbin/e-smith/expand-template /etc/squid/squid.conf
/sbin/e-smith/signal-event remoteaccess-update
service squid stop
Still nothing.
I would like to report great uptime but I panicked and rebooted anyway.
Still nothing.
On the client, I went to a static internal IP and setup my ISP dns.
Still nothing.
Hmmmm... I disconnect the SME from the network by uplugging it from the port. Everything works. Reconnect it, web stops working again.
I'm pretty sure it's a dns config / dns component problem.
Anyone have any ideas?
