Hi, im running OpenVPN as a client on my WRT, the server is pushing the dns server dhcp option to the client however it is not being set. When the OpenVPN client connects i would like the dns server to be used over the VPN rather than my local router's dns server, any direction which scripts should i add/edit?

I need dnsmasq to be running as i would like lan clients to use the WRT as the dns server. I simply want the requests to be forwarded to the server on the lan but the /tmp/resolv.conf files are not changed.

Current files are:

# cat /tmp/resolv.conf
nameserver 127.0.0.1
search lan

# cat /tmp/resolv.conf.auto
nameserver 192.168.1.1

i am running White Russian 0.9

Thanks in advance

Right i have managed to read the option in the up-script for the openvpn client and it works, i set in the up script:

dns1=`echo ${foreign_option_1} | sed -e 's/dhcp-option DNS //g'`
echo nameserver $dns1 > /tmp/resolv.conf.auto

and all is good smile

Cheers
