Summary0004396: error: Invalid ip or netmask
DescriptionWhen using tun in openvpngw2gw with endian as Client server this is shown on the log:

Jul 20 14:29:07 efw tix[6483]: Fri Jul 20 14:29:07 2012 event_wait : Interrupted system call (code=4)

Jul 20 14:29:07 efw tix[6483]: error: Invalid ip or netmask ''
Jul 20 14:29:07 efw tix[6483]: run-parts: /etc/openvpn/ifdown.client.d//00bridge exited with return code 2
Jul 20 14:29:07 efw tix[6483]: Fri Jul 20 14:29:07 2012 /sbin/ip addr del dev openvpntun0 local peer

Not knowing the code noticed however something that may cause this issue:

 except ValueError:
        parser.error("Invalid ip or netmask '%s %s'"%(ip, mask))

should the "mask" be there?
as the script is expeting ip,mask but it's pushed ''

According to the OpenVPN documentation, for tun, the openvpnbridge script is execute with the following parameters:
tun_dev tun_mtu link_mtu ifconfig_local_ip ifconfig_remote_ip [ init | restart ]

For tap, the parameters are:
tap_dev tap_mtu link_mtu ifconfig_local_ip ifconfig_netmask [ init | restart ] accepts both the tun/tap parameters:
usage: <options> <device> <mtu> <mru> <local_ip> <local_netmask|remote_ip> [init|restart]

When I disconnect the client, the script is called with the following parameters:
--remove openvpntun0 1500 1542 init
