DCHP Clash with User IP

Joemadden1989

We have a 10.59.58.32/29 subnet. The Server is configured like this:

local 1.1.1.2
port 1194
proto udp
dev tun9
mode server
tls-server
topology "subnet"
ca /111.pem
cert /112-cert.pem
key /112-key.pem # This file should be kept secret
dh /113.pem
ifconfig 10.59.58.33 255.255.255.248
ifconfig-pool 10.59.58.34 10.59.58.38 255.255.255.248
ifconfig-pool-persist /114.txt
push "topology subnet"
push "route-gateway 10.59.58.33"
push "route 10.48.0.0 255.240.0.0"
keepalive 10 120
tls-auth /115.key 0 # This file is secret
comp-lzo
max-clients 32
;user nobody
;group nobody
persist-key
persist-tun
status /111-status.log
verb 4
mute 20
hand-window 60
tls-timeout 2
tls-verify "/usr/bin/verify-cn 113"
crl-verify /112.crl

I believe that the server should then use 10.59.58.33 leaving 10.59.58.34 to 10.59.58.38 free for client use.

ERROR: There is a clash between the --ifconfig local address and the internal DHCP server address -- both are set to 10.59.58.38 -- please use the --ip-win32 dynamic option to choose a different free address from the --ifconfig subnet for the internal DHCP server

Does OpenVPN always claim the last available IP for the DHCP server?

Thanks

Just setup my server like so:

               ifconfig 10.101.103.33  255.255.255.248
          ifconfig-pool 10.101.103.34 10.101.103.38 255.255.255.248
               topology subnet

works fine ..
