Hello,
I am trying to implement DHCP via local bridge. The vpn server is installed on a CentOS7 Server running in a VirtualBox. The Server has the following network interfaces:
$nmcli -d
DEVICE    TYPE      STATE      CONNECTION         
enp0s3    ethernet  connected  Wired connection 1 
enp0s8    ethernet  connected  Wired connection 2 
tap_tap1  tap       connected  tap_tap1           
The vpn server listen on the enp0s3 interface at port 443.
First I tried to directly run a DHCP server on the bridge network interface. But it seems that it doesnt work this way.
Now I want to use the DHCP Server which is already provided by VirtualBox and reachable via enp0s8 (with ip 10.0.3.2)
Question: How do connect the bridge to the device enp0s8 ? Is this an issue of iptables/NAT ?
Thanks,
plichel
Edit:
After rereading the vpn usermanual, I better understood how the bridge is working.  For some reason I thought there has to be a special tun/tap device, which bridges between two networks.
However, by using the BridgeCreate Command  and simply specifying an already available network interface (which might be connected to network where a DHCP server is possible running), I got what I want.
Thanks for your attention and much more thanks for this great software !
Regards!
