Is it possible to have netfilter generate keepalive packets for connections? I have some proprietary windows services that communicate with each other through a few Linux routers, and I suspect that some connections are timing out (or being selected for purging from the connection tracking due to other more-active connections). If netfilter could generate a keepalive in each direction sometime before timing out the connection it would be great! Any other suggestion appreciated too. The WRT54GL router will be replaced before too long with something with a lot more memory which should resolve those problems but I need an interim solution. Thanks James
