[Bug 445695] [NEW] redirect-gateway does not work

[Šarūnas Burdulis]

Public bug reported:

Binary package hint: openvpn

With 'redirect-gateway' option (either pushed from the server or in
local config) openvpn does not execute 'route del/add...' to change the
default route. Server and client configuration files attached. Below is
a comparison of client log files (grep for 'route').

Ubuntu 9.04, openvpn 2.1~11-1ubuntu3 (redirect-gateway works):
