...onding that bonding wasn''t made for. I just want to give it a try. I want a simple mechanism to have a failover on a 24Mbit line to a 2Mbit line in case the 24Mbit line goes down.

...ring up a VPN, start an OpenVZ server, then start virtual environments (VEs) within that. The VEs have addresses from our campus network. Some now also have Amazon (EIP) addresses so that we can reach them without traversing the VPN. Originally I used OpenVPN and configured the VPN interface (tap0) with DHCP. tinc does not appear to have a clean way of running commands after an interface is active and I don't really need a valid address for the VPN interface anyway, so I decided to just use a non-routable address. This is also cleaner because I don't have to delete the interfa...

Here is the scenario: I have one server with kernel 2.4.24 with a bridge br0 made of 2 interfaces, eth0 and tap0 (the last is an OpenVPN tunnel), and one remote computer connetting through tap0. If I assign a static IP to the remote computer, the bridge works perfecly (so I think the problem is not OpenVPN-related). If I start a DHCPd on the server and I configure the remote client to get the IP from it,...
