*(sorry, the previous message is gone a bit fast)* hi, where can I get help for this ? my problem is : I'm on a corporate network that is filtered (proxy) and I need to run some tests on a virtual machine that needs to have direct access to the Internet. I set up this configuration and try to route everything that comes out of tap0 to wlan0 and then to Internet. - - \ / \ / \ / +--------\-------+ +-------/-------+ |free GW | |corporate GW | |192.168.144.254 | |10.10.10.254/24| <http://10.10.10.254/24%7C> +--------|-------+ +-------|-------+ \ / +---------------|-----------------|------+ |HOST |wlan0 | |eth0 | | |192.168.144.1/24| <http://192.168.144.1/24%7C> |10.10.10.1/24| <http://10.10.10.1/24%7C> | +----------------+ +-------------| | | | +-----------------+ | | |tap0 | | | |192.168.11.254/24| <http://192.168.11.254/24%7C> | | +--------|--------+ | | | | | +-------------|--------+ | | |VM |eth0 | | | | |192.168.11.1/24 | | | | +-----------------| | | +----------------------+ | +----------------------------------------+ here are the commands used: # ip tuntap add tap0 mode tap user me # ip addr add 192.168.11.254/24 dev tap0 # ip link set tap0 down # echo 11 tap0 >> /etc/iproute2/rt_tables # ip rule add from 192.168.11.254 lookup tap0 # ip route add default via 192.168.144.254 dev wlan0 proto dhcp src 192.168.144.1 # echo 1 > /proc/sys/net/ipv4/ip_forward # iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE I can ping 8.8.8.8 from my virtual machine but all traffic (host/corporate) now seems to flow through wlan0 (tshark -i wlan0)... regards, lacsaP.
