Load Balancing , MSN and SSL

HI All ,

I am running a FC6 box with two internet links with load balance . Every
thing is working fine expect the MSN connection that failed and reconnect
every time and SSL connections .  I would link to know if with the nona
howto I could fix that .

I have been tried with no success to redirect that connection only to one
link but its look like do not work . Here my configuration :

#!/bin/bash

I add the rules from DNS and FTP too .

But it''s not seems to work .

Any help will be appreciated .

My experience with the layer7 module has been sketchy.  Have you checked to
make sure that the layer7 module is catching msnmessenger traffic?  It would
be a good idea to try

#iptables -A PREROUTING -i eth1 -p tcp -m layer7 --l7proto msnmessenger -j LOG \
- --log-prefix ''MSN Messenger Packet: ''

and consult /var/log/messages and make sure that layer7 is seeing it.
If it''s not, the packets for msn traffic will never get marked.

a much better solution would be to mark based on destination port, and let
connection
tracking take care of the rest. for example:

#DNS Traffic
#iptables -A FORWARD -i eth1 -p tcp --dport 53 -j MARK --set-mark 2
#iptables -A FORWARD -p tcp -m state --state RELATED,ESTABLISHED -j ACCEPT
#iptables -A FORWARD -p udp -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT

hope this helps!

Re: RE: Load Balancing , MSN and SSL

Hi, I think you could mark packets based on ports 1863 and hosts
messenger.hotmail.com , gateway.messenger.hotmail.com, webmessenger.msn.com
