Nice work on netifdizing OpenVPN! I'm really looking forward to patching all of your scripts from http://pariah-angels.de/openwrt/openvpn-interface.tgz into my AA-rc1 installation I have here. Any chance you might want to publish an AA ipk for it? :-)
I wonder what your thoughts are on the applicability of your existing work to a router with > 1 "external" (i.e. Internet) interfaces (and therefore more than one external IP address). In such a case, (AFAIU, anyway) one typically chooses one of the interfaces and tells OpenVPN to bind to it. Also, being totally new to this netifd stuff, I am just trying to figure out the facilities available to "proto" scripts, so I could totally be missing it here, but does your proto script have a dependency on an Internet interface being up? That is, will "ifup" for an OpenVPN interface only succeed if a "real" interface, providing connectivity upstream, is already plumbed? In a message thread on the -users lists where I was trying to get an HE IPv6 tunnel up, Jow showed me where the 6in4 proto fails unless there is a route to 0.0.0.0 present using: ( proto_add_host_dependency "$cfg" 0.0.0.0 ) I wonder if that is applicable here. But more importantly, for > 1 external interface systems, having a dependency on interface OpenVPN intends to bind to would be even more important. Looking forward to your thoughts. Cheers, b.
