Dear List, Does anyone know whether there is patch that will allow kernel 2.4 or greater to support setting up of multiple IPSec tunnels (passthrough) to the same destination - ie more than one machine behind the firewall trying to set up IPSec tunnel to the "same" remote host? When I was testing kernel 2.4.20 for passthrough capability a few months back, there was no patch that would allow me to do that (single passthorough worked fine). I presume this has something to do with writing a conntrack IPSec helper? Regards, Dhiraj Bhuyan BTexact
