Hi,
Ive got squid proxy server running on a CentOS 4.4 machine. This proxy
server is connected to the internet through a Sonicwall PRO3060
firewall machine.
We have got three different ISP lines, one of which is used by squid.
All the three lines terminate at the firewall. One of these links then
goes to the squid server.
Many a times it happens that the internet link on the squid line goes
down, because of which we have to switch the squid server on to one of
the remaining ISP lines.
I was planning a setup in which an extra NIC would be attached to the
squid server. This NIC would be connected to a different ISP line, so
that when one link goes down, the squid proxy server automatically
switches on to the next line, wherein the LAN users dont get to feel
the difference while browsing. Also, when the original link gets
restored, the squid server automatically switches back on to the
original link
My current setup requires me to deny access to the squid server till
the time it is up again.
Is this setup possible? And if yes, can you please tell me how or
point me to the necessary resources.
Thanks
