Your computer only knows about devices in the 10.10.1.0/24 range, which the gateway device is not in. The DNS server is also (far) outside that range. Your PC can't see the gateway and therefore can't route packets to the DNS server. Hence the unknown host when trying to ping google. Try sticking in a static route to the gateway device. Code: #route add 10.10.10.1 dev eth0 #route add default gw 10.10.10.1 This change isn't permanent yet, but try it out and tell us if it works and we can look at making the changes you need. If there are any errors, post them and we'll try to help. Chris... __________________ DRM keeps an honest user loyal

I'm glad that worked out, although I probably should have mentioned that the changes wouldn't be permanent (in case it all went horribly wrong).

Slackware isn't really set up for this sort of thing because it's a fairly rare setup. This means we will have to do a spot of script editing.

The one you are interested in is /etc/rc.d/rc.inet1. Here is how mine looks just now:

Code:

#####################
# GATEWAY FUNCTIONS #
#####################

# Function to bring up the gateway if there is not yet a default route:
gateway_up() {
  if ! /sbin/route -n | grep "^0.0.0.0" 1> /dev/null ; then
    if [ ! "$GATEWAY" = "" ]; then
      echo "/etc/rc.d/rc.inet1:  /sbin/route add default gw ${GATEWAY} metric 1" | $LOGGER
      /sbin/route add default gw ${GATEWAY} metric 1 2>&1 | $LOGGER
    fi
  fi
}

# Function to take down an existing default gateway:
gateway_down() {
  if /sbin/route -n | grep "^0.0.0.0" 1> /dev/null ; then
    echo "/etc/rc.d/rc.inet1:  /sbin/route del default" | $LOGGER
    /sbin/route del default
  fi
}

You need to set up the static route before setting up the default gateway. Changes are highlighted

Code:

#####################
# GATEWAY FUNCTIONS #
#####################

# Function to bring up the gateway if there is not yet a default route:
gateway_up() {
  if ! /sbin/route -n | grep "^0.0.0.0" 1> /dev/null ; then
    if [ ! "$GATEWAY" = "" ]; then
      echo "/etc/rc.d/rc.inet1:  /sbin/route add default gw ${GATEWAY} metric 1" | $LOGGER
      /sbin/route add ${GATEWAY} dev eth0
      /sbin/route add default gw ${GATEWAY} metric 1 2>&1 | $LOGGER
    fi
  fi
}

# Function to take down an existing default gateway:
gateway_down() {
  if /sbin/route -n | grep "^0.0.0.0" 1> /dev/null ; then
    echo "/etc/rc.d/rc.inet1:  /sbin/route del default" | $LOGGER
    /sbin/route del default
    /sbin/route del ${GATEWAY}
  fi
}

Test the changes and if it all looks good you should be good to go. Don't forget to backup the rc.inet1 file before editing it.

Let us know how you get on,

Chris...

Hi guys, I`ve been reading around and i found out that this problem that rommeo had is the same as mine, although the solution is not. Can you guys give me any hints on how to setup a network and an internet connection ? Toni.
