* Added support for "on-link" routes on Linux clientJames Yonan2012-01-271-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | These are routes where the gateway is specified as an interface rather than an address. This allows redirect-gateway to work on Linux clients whose connection to the internet is via a point-to-point link such as PPP. Note that at the moment, this capability is incompatible with the "redirect-gateway block-local" directive -- this is because the block-local directive blocks all traffic from the local LAN except for the local and gateway addresses. Since a PPP link is essentially a subnet of two addresses, local and remote (i.e. gateway), the set of addresses that would be blocked by block-local is empty. Therefore, the "redirect-gateway block-local" directive will be ignored on PPP links. To view the OpenVPN client's current determination of the default gateway, use this command: ./openvpn --show-gateway git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@7794 e7ae566f-a301-0410-adde-c780ea21d3b5 Signed-off-by: James Yonan <james@openvpn.net> Signed-off-by: David Sommerseth <davids@redhat.com>

Most of the files had minor changes, but due to the CRLF unification patch (commit 6b2883a637fe73492) we got an increased number of conflicts. In addition inclusion of IPv6 support makes the creates a lot of merge issues in route.c and socket.c This merge also reverts commit 7c18c6353904f8c6e7 which merged add_bypass_address() into add_host_route_if_nonlocal(). However the SVN tree began to use add_bypass_address() another place, where at first glance it did not be appropriate to use add_host_route_if_nonlocal(). This merge has gone through a 'make check' without any errors, but have not been tested more thoroughly yet.

| * Added redirect-gateway block-local flag, with support forJames Yonan2011-06-121-25/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux, Mac OS X, and Linux. This flag (which is pushable from server) blocks client access to local LAN while VPN session is active. Added standalone --show-gateway option to show info about default gateway. Extensively refactored get_default_gateway function in route.c to ease implementation of block-local. Removed "Experimental" disclaimer from redirect-gateway man page. Version 2.1.3y. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@7334 e7ae566f-a301-0410-adde-c780ea21d3b5

* Windows IPv6 cleanup - properly remove IPv6 routes and interface configGert Doering2011-05-221-0/+1

Needs to make delete_route_ipv6() visible from tun.c (route.c, route.h) and to properly zero-out host bits from IPv6 "network" at interface route clearing. Further, add IPv6 routes with "store=active" to make sure nothing lingers after a system crash while OpenVPN was running. While at it, small Solaris cleanup - use CLEAR() to zero-out "ifr" struct.

* The maximum number of "route" directives (specified in the configjames2009-09-171-8/+10
| | | | | | | | | | | | | | | | | file or pulled from a server) can now be configured via the new "max-routes" directive. Previously, the limit was set to 100 and fixed by a compile-time constant. Now the limit is dynamic and can be modified by the "max-routes" directive. If max-routes is not specified, the default limit is 100. Note that this change does not address the maximum size of the pushed options string sent from server to client, which is still controlled by the TLS_CHANNEL_BUF_SIZE compile-time constant. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@4967 e7ae566f-a301-0410-adde-c780ea21d3b5

* Added new 'autolocal' redirect-gateway flag. When enabled, the OpenVPNjames2009-05-241-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | client will examine the routing table and determine whether (a) the OpenVPN server is reachable via a locally connected interface, or (b) traffic to the server must be forwarded through the default router. Only add a special bypass route for the OpenVPN server if (b) is true. If (a) is true, behave as if the 'local' flag is specified, and do not add a bypass route. The new 'autolocal' flag depends on the non-portable test_local_addr() function in route.c, which is currently only implemented for Windows. The 'autolocal' flag will act as a no-op on platforms that have not yet defined a test_local_addr() function. Increased TLS_CHANNEL_BUF_SIZE to 2048 from 1024 (this will allow for more option content to be pushed from server to client). Raised D_MULTI_DROPPED debug level to 4 from 3.

| | | | | | | | | | | | | | | | | | | | | | * Warn when ethernet bridging that the IP address of the bridge adapter is probably not the same address that the LAN adapter was set to previously. * When running as a server, warn if the LAN network address is the all-popular 192.168.[0|1].x, since this condition commonly leads to subnet conflicts down the road. * Primarily on the client, check for subnet conflicts between the local LAN and the VPN subnet. Added a 'netmask' parameter to get_default_gateway, to return the netmask of the adapter containing the default gateway. Only implemented on Windows so far. Other platforms will return 255.255.255.0. Currently the netmask information is only used to warn about subnet conflicts. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3179 e7ae566f-a301-0410-adde-c780ea21d3b5
