It does not care anymore. The instructions on the website are working. It's
me that I totally forgot to add the IP on the VIF statement of the
debian.cfg file. As soon as I added it and I changed $main_ip with $ip on
the vip-route-local,the network started working like a charm.
To work the vif-route script should be modified like this :
netdev=mlan0
main_ip=$(dom0_ip)
case "${command}" in add|online)
ifconfig ${dev} ${main_ip} netmask 255.255.255.255 up
echo 1 >/proc/sys/net/ipv4/conf/${dev}/proxy_arp
echo 1 >/proc/sys/net/ipv4/conf/${dev}/forwarding
echo 1 >/proc/sys/net/ipv4/conf/mlan0/forwarding
echo 1 >/proc/sys/net/ipv4/conf/mlan0/proxy_arp /usr/sbin/arp -i mlan0 -Ds
Thanks anyway.
