I am quite new at setting up openVPNs. I came quite far but now I hit a wall and I can't find out where to look next. So I try to describe my problem as good as possible. Just say if you need further data.
Goal:
- -openvpn on home server in bridge mode.
-dhcp assigned addreses for vpn clients.
-access to hosts on local (vpn server-side) subnet.
Status quo:
- - vpn client to vpn server connections complete successfully.
- Client gets an dhcp-server-assigned ipv4 address (dhcp, dns, etc servers running on same host as openvpn server).
- no connection possible between <vpn-client> and <hosts on subnet> except <vpn-server> itself
- connections between <vpn-client> to <vpn-server> work fine
- connections between <vpn-server> to <vpn-client> work fine
- connections between <vpn-server> and <hosts on subnet> work fine
- ping from vpn-client to host on subnet: 'Destination host unreachable', 'Request timed out'
- - OpenVPN HowTo and the recommended iptable rules
- tcpdump on tap0 and br0 to sniff for packets from the vpn-connected client. On connections between vpn-client and vpn-server there were packets. On connections between vpn-client and another host on the subnet there were no packets.
- trying out different mtu related settings without a positive result
- no restricting iptables rules
- I found this post <topic10486.html> which is quite similar (except address assignment) to my problem but no solution so far.

I set bridge_hw manually because br0 sometimes had the randomly assigned mac of tap0 and some other time the correct mac of eth0. This was quite confusing at first when it sometimes worked and sometimes not and I had no clue what was going on but finally found that after comparing ip address output.
Ideally I would rewrite this to something like
bridge_hw eth0
if possible.

I am a bit confused about this line
Thu Jul 17 21:45:33 2014 Extracted DHCP router address: 192.168.0.1
The dhcp server is running on 192.168.0.4 (also the host which runs the openvpn server is running). 192.168.0.1 is the isp-modem-router which has dhcp capability but which is disabled.
