Description
Actual implementation changes firewall rules accordingly to Mode property of openvpn service.
When Mode is set to bridged, all firewall rules are targeted for tap devices and when Mode is set to routed, all firewall rules are targeted for tun devices.
This behavior doesn't allow environments with multiple vpn of mixed type.
here a working patch to fix the problem:

Please, test the package with latest packages (base, lib and nethgui) from testing repository to ease bridge configuration.
Test case- Configure OpenvPN server in bridged mode (remember to create the bridge)
- Connect to the server with a roadwarrior client
- Configure a net2net VPN in routed mode
- Check both VPNs are working

While the issue is about /etc/shorewall/interfaces, the commit msg is about zones.
Shorewall complains (syntax error).
Work around:
$ cat /etc/e-smith/templates-custom/etc/shorewall/zones/99openvpn ovpn ipv4
