iptables-NAT and MSN losing state

Hi,

For some time now i've attempted to get a mix of win/mac msn-clients to get trough a netfilter-nat-box without being 'signed off' repeadetly.

Is there any resource on what to do in this situation ? It is damn near impossible to find. AFAIR there used to be an issue with ssl or msn-http-proxy wich was possible to fix by means of an echo > proc... to increase the time-out but i'm not a netfilter-guru as such thus it is unclear to me what to do next.

The setup is a 2.4.24-kernel with iptables 1.2.6a and reaim 0.8 with all rules applied to enable msn-type traffic.

Please advise.

Best Regards,

J.L.
