OpenVPN and Local network on the same C Class

[Carlo]

Hi everybody,

I'm currently using PPTP vpn server for our users to connect to our network. Because of the problems which are caused with users behind NAT i would like to switch to another VPN solution. I have run some tests with OpenVPN and they are looking good. Now I have one problem, that is I need those VPN clients in the same C class network as the rest of my LAN just like PPTP clients. I need this because we have an MPLS connecting us to other sites which only know our C class network. I see in this forum the optimal solution would be bridging which would allow just what i need but it seems not stable enough to use. What leaves are these 2 options (I think).

1. Preform a NAT so that the IP's are masked (I really don't see how to set this up).
2. Divide my Class C network up into smaller subnets so that my OVPN subnet is a different subnet but still in the C class.

2 sounds like an option to me but I'm not sure if this will work. As example subnet's I would take:

Server DMZ:    10.1.1.0/26
OVPN:            10.1.1.64/27
Spare subnet:  10.1.1.96/27
LAN:              10.1.1.128/25

Does this make sense?

And if so how would i need to configure OVPN to access all these subnets?

Any input appreciated!

it will work fine, i run mine like this as well.

192.168.125.0/25 LAN
192.168.125.128/27 VPN

as far as how to access the other non-LAN subnets, youll just need to tinker with it… but it doesnt sound unresonable.
