Hi all,

I have to manage a so-called e-business application on a LVS cluster. On one
side, I have a DR socket (TCP) connection, and on the other side, a NAT
HTTP-like (SOAP or alike) connection.

The application should have been suitable for clustering (dynamically sharing
sessions), but it doesn't seem to work as expected (did I say it is Java
written?).

Anyway, I could use fwmarks to manage that. It meens that the NAT part goes
DR. Then, because the director is the default gateway, and have to stay the
default gateway, I have martian packets (packets coming from the realserver
with a source address that is also local to the director).

I read the HOWTO, and would like to know what would be the best way to manage
matians packets nowdays. I didn't find so much documentation about martian
patches or options for 2.4.26 kernel. I would love a simple module :).

Any tip appreciated,

François.
