robina80

hi all,

i have succesfully got working site to site and i can connect each way ie from site a to b and b to a via pings/traceroute/web servers/putty via the LAN IP's of each building ie site a 172.16.24.0/24 and site b 192.168.0.0/24

in site a i have an access server and site b i have a centos 6.6 with openvpn installed, i have copied the client.ovpn file over, disabled iptables and then i run the config file

openvpn --config /etc/openvpn/client.ovpn

it connects fine, i attach the screenshot

What is your DNS server address and what DNS names are you trying to resolve ?

BTW: That screen shot is a copy of your client log file .. as you are there, why not upload the log ..

the dns servers are 172.16.24.1 and 172.16.24.2

the thing is on site b when there connected to vpn they can ping any ip in site a but not the dns names

but if i add the dns servers manually to the machine in question then they can ping site a's dns names

Double check your client log for multiple push "dhcp-option DNS x.x.x.x" .. I can see six items ..

ive only added two dns addresses to my openvpn access server to push, i dont know what 208... is as i havnt added it and it appears 4 times, why is this!!!

how do i check the client log please, where would i locate it, ie /var/log/...

sorry i can no longer edit my post, hence why im writing to conclude from my last message

im adding my dns information to the access server on the page

vpn settings > dns push - im using the option use same as host as my host is using the same dns ip addresses i gave

do you think i should delete my dns entry there and add it to this page

advanced vpn > additional openvpn config directives

if so where should i put my command

push "dhcp-option DNS 11.22.33.44"

under the server config directive or the client config directive

and once i update my server, do i need to restart my client for it to take in the new settings?

thank you
