Hi,

I'm using shorewall 4.5.21.5 (on F20, FWIW, but that probably doesn't
matter much).

I have OpenVPN on my shorewall-protected router with a number of remote
connections (that all connect to me as they are all effectively road
warriors with dynamic IPs).

I've added zone entries as such:

vpn1 ipv4
vpn2 ipv4
vpn3 ipv4
vpn4 ipv4
vpn5 ipv4
vpn6 ipv4
vpn7 ipv4

and then interfaces as such:

vpn1 tun0
vpn2 tun0
vpn3 tun0
vpn4 tun0
vpn5 tun0
vpn6 tun0
vpn7 tun0

That yields an error about duplicate interfaces (tun0) in the interfaces
file.

I actually used to have:

- tun0

in my interfaces file on previous versions of this configuration and
shorewall but that seems to emit warnings about empty zones when I try
to install it and missing "loc2vpn$n" chains where I specify what my
local subnet is allowed to do on the VPN subnets.

I did look at http://shorewall.net/OPENVPN.html but I didn't see
anything there about how to handle the case of multiple OpenVPN clients
where you want to put them into different zones because they have
different rules.

Any ideas?

Cheers,
b.
