OpenVPN server IP pool expansion

cr9c1

Hello. I have searched high and low and cannot find an answer. (Well, I did but it didn't work).

I have followed the ubuntu openvpn server install. It installed, functions, everything is fine. However, I am anticipating more than 64 users (for the sake of argument) and want to expand my local IP pool that OpenVPN hands out when a client connects. For arguments sake, lets say 192.168.5.0/24 is what I have now. I wanted to configure a /23, or a /22, so I thought I'll just change the netmask on the "server 192.168.5.0 255.255.255.0" statement in server.conf and be done with it. No such luck, server failed to start, invalid argument.

How do I make the block of IPs that openvpn hands to clients larger? I'm not using a bridged mode, or routed mode. Its a simple point to point tunnel to access some other network resources that are already routed and mapped correctly. I need help. 🙁 I appreciate any assistance in advance.

assigning different netmask IS a solution.

please post your configs

I'm good. Thanks for the help. I figured out my issue was the way I had subnetted the private lan. I wasn't following proper rules and had an overlapping subnet in my .254 network. I got it figured out. Thanks for the reply though. The next issue is getting it to see my LAN.

Currently, I have the VPN server with 2 nics. One connected to the internet, one connected to my LAN, but my VPN clients can only see my router and not my LAN clients, so thats going to be interesting.
