reliable WAN ping address or multiple WAN ping address in Sc

Hi,

I use the enhanced failover script from the WiKi which works fine in itself. But the used IP is from Google and that´s not so reliable as I would expect. I run pingmonitor on it and see it not returning pings at times.
I tried to use my ISP dns addresses but they go down at times as well.
I even tried somebody else’s ISP address but even so, failures at times.

When there is a failing sequence of 5 pings my networks routes out to another WAN gateway but that’s only because the specific server in the script doesn´t return the ping. I can still browse or ping other nodes on the WAN, even through the gateway that is supposed to be down. (it´s route is just down, a PC on the WAN side of the routed but on the LAN side of the ADSL modem can still function normal, apart from the failing ping to that specifice node.)

Does anybody has a very reliable ip that is virtually always up?

Or who can write me a script that for instance checks two nodes before the route cost in the ip/route/default route cost is changed? I´m a no-know in scripting so could use some help here…

cant you ping the gateway ? pinging anything 2+ hops out isn’t going to be very reliable.

I have two ADSL connections to a router, these are the gateways of my network. One is the default one, the other just as failover.
The idea is to ping the connectivity through the working (main, or default) gateway and in case the ping doesn´t return the standbye gateway connected to the other ADSL line should take over.
The default gateway is direct wired into the router and therefore in itself more reliable then the standbye gateway since that one has a 15km backhaul link (wireless) to a remote ADSL modem.

The problem is that at time the local ADSL is shut down by the telcom operator due works etc.
I don`t want manually monitor the status of the main ADSL to switch it if needed.

Pinging the ISPs dns servers didnt prove very reliable since they go down at times too.
