Bug #2514

static routes for monitor IPs should be removed
0%
Description
Since apinger in 2.0 and newer binds to specific IPs, and the policy routing for firewall-sourced traffic bound to a specific IP takes care of proper routing, the static routes for monitor IPs are unnecessary and should be removed.
There is a related bug in that they aren't removed when a monitor IP is changed, but that goes away if the routes aren't added at all anymore.

I have just upgraded a 2.0 Final installation to "Sun Sep 16 19:35:57 EDT 2012" and everything seems to work fine now after fixing a few upgrade issues with the gateways.
To get to the point;
I see that no static routes are added for the custom gateway monitoring IP's although the log shows the opposite:

There was an attempt to remove it in the past but seems it had side-effects (see ticket #3179 and 32a9eb1873).
I've fixed the issue of not removing it when monitor IP changes.
