I hope i wont make it too complicated and sorry for my englihs...

if anyone could help!

Multiple Internet Connection, established connection dropping issues
...ser drops the connection. At which time if
the connection is re-established by the user the linux router then could
use a different interface but it should only use the interface that the
connection was established under.
I have made some progress playing around with the gc_interval gc_timeout
and gc_elasticity.
I also started looking at the code behind the routing and gc logic in
the route.c file in the linux kernel source. It appears that the gc does
not compare which routes to keep or which routes to drop. It just does
sort of a first come first out sweep.
Also it is my assumption from the code...

Route cache
Hi,
I have a P4 @ 3Ghz router running Debian. It shapes traffic ( about
500-600 classes ), about 1000 iptables rules, and it does BGP too, so i get
about
1300+ routes in the routing table. The problem is the load is too high on
this system. I found a solution to my problem, turning off the route cache,
but i dont know how to implement it,
I was wondering if anyone found a way to disable the

Application 500 Errors
Configuration:
(2) Dual Core Opterons
8GB RAM
Apache used to balance 40 mongrel instances
We receive Application 500 Errors. Nothing suspect appears in the log, so we
are at a lost as to what to do next.
Any advice would be welcome and/or an explanation of what types of things
cause Application 500 Errors in mongrel.
Thanks!

Split access, load balancing AND forwarding: HOW?
The LARTC howto correctly describes load balancing and split
access for traffic from a machine with multiple ISP connections
(http://www.lartc.org/lartc.html#LARTC.RPDB.MULTIPLE-LINKS) --
*provided* the traffic originates from the machine itself (i.e.
traffic regularly handled by the INPUT and OUTPUT chains of
iptables).
When forwarding traffic from an attached local network, the
following
