I have a somewhat tricky proble to solve.
We have a wireless link between 2 building. One of them has an mikrotik and below there are some vlans. Some machines of one vlan need to use openvpn to connect to a remote private lan. I put a TP-Link WR1043ND (which those machines connect to) with openwrt with ebtables just in case I need it.
I've configured openwrt in such a way that all ports belongs to the same vlan. My idea was to make things as transparent as I can.
It has a bridge as follows:
usr/sbin/brctl-full show br-lan bridge name bridge id STP enabled interfaces br-lan 8000.f8d111565716 no eth0.1 eth0.2
Also I've added an ebtables rule:
ebtables -t broute -A BROUTING -p ipv4 -j DROP
So "bridge" has only one IP address. I've installed openvpn and I'm trying to bring up the tunnel but I can't still get working.
Sure, someone can says why don't you use the vpn on the mikrotik, there are some reasons, the first one is I have little experience with mikrotik and I'd want to have the vpn at hand :)
The problem is that openvpn is not working, because it is complaining that I have only one Ip Address on the server side. So I set up and alias interface with another IP address but is not working either:
: Rejected connection attempt from IP-Client-Side:37801 due to --remote setting
Is there a way to make it work?
