Could someone look at my config and check to see if:
1) the bridging is done correctly
2) firewall settings to enable DNS and ICMP over the bridge
3) Also make it so a client doesn't route it's DNS over the bridge, I would only like to resolve local network names, I don't want all browser traffic to go through the openvpn link.
