Hi! This could come a little "off-topic", but: which VPN are you using? if you happen to be using OpenVPN, try adding the option "persist-tun", also, there is a chance that you can make squid actually restart when the VPN goes down and up again (by using the "down" and "up" options, that calls down and up scripts). Anyway, please keep us informed! I hope this helps, Ildefonso Camargo On Mon, Dec 7, 2009 at 11:22 AM, <tyler@xxxxxxxxxxxx> wrote: > > >> -------- Original Message -------- >> Subject: Re: squid ceasing to function when interface >> goes down >> From: Amos Jeffries <squid3@xxxxxxxxxxxxx> >> Date: Sat, December 05, 2009 5:02 pm >> To: squid-users@xxxxxxxxxxxxxxx >> 1) server_persistent_connections off.
