We have Linksys RVS4000 routers connecting our two offices via an IPSec tunnel. They're flaky at best, and I'd like to replace them with Eboxes, but I need to set the sites up one at a time. It's crucial that the tunnel stay up between the two sites, as time clock information is transferred between them on a daily basis, and can only be done via IPSec. Is it possible to have an Ebox at one site and the RVS4000 at the other site with an IPSec tunnel between them? I'm pretty new to Ebox and OpenVPN, and the little time I've spent with the two doesn't show me an easy way to do this. I'm wondering if anyone knows of a workaround.
