I say it's the router, our vendor says it my set-up. I have a 3Com router
that contains a firewall and VPN capability. It is the link between my DSL
modem and the rest of my network. For over eight months, things have been
working fine with my network setup with static IP's (relatively small
network).

The router is configured with the DSL login info, DNS's etc. The
workstations are configured to use the router's local IP (all local is in
the 192.168.xxx.xxx range) for the gateway and the primary DNS. This has
been working fine until recently we get intermittent loss of DSL service. By
intermittent, some workstations get email, some don't; some people can
browse, some can't; some get email but cannot browse, etc.

By unplugging the power to the router for a few minutes and plugging it back
in and rebooting, everything comes back to normal. At least for a while, it
may last a day, it may last two hours.

I say there is a problem with the router. My vendor who sold me the router
says the only way to fix it is to start using DHCP. If this was the case,
why would it have worked fine for over 8 months.

Any suggestions ?

Thanks,

Doug
 
That has worked in the heat of the moment to get connected. But I really
shouldn't have to re-configure each workstation to point to our ISP. That's
what the job of the router is, isn't it ? As we grow, I don't want to have
to adjust 100 workstations if we change ISP's.

Any other thoughts ?

Thanks,

Doug

No, the basic job of the router is to route traffic between networks - not
to proxy DNS.

That's what DHCP is for - your router should be able to do it. :-)
Any other thoughts ?

What if you change the DNS server IPs to those of your ISP instead?

Ok, My error on one point that may affect the analysis. The device is
actually a "3Com Office Connect Cable/DSL Secure Gateway" Therefore I do
believe it is the job of this device to proxy the DNS.

Please review the original issue below that I have been having.

Thanks,

Doug

Doesn't really make any difference - my original comments still apply. I
wouldn't bother trying to have the gateway do any DNS 'proxying' - what's
the purpose? It doesn't do anything for security, and it isn't working. :-)
