Hello dear linuxquestions.org community, I wonder if it is possible to prevent dhclient from setting the default gateway and dns servers when leasing an ip address, I actually just want it to set the ip address and if possible a static route.

Configuration:

eth0 dsl connection (dhcp)
this should be the Internet gateway.


wlan0 wireless network with secondary internet connection (dhcp)
this is only an on demmand connection to a specific Internet site, however whenever I issue the dhclient wlan0 command, my resolv.conf gets new dns information as well as a new default route is added, that makes my eth0 connection useless. does anybody knows how to prevent this from happening?

Thanks you.

Well it seems that functionallity is not available on dhclient, I found that dhcpcd will prevent the setup of resolvers and defaultroutes used like this:
dhcpcd -R -G wlan0

Cheers
