Nelson, I've never played with the TUN method before but I know you need to create the tunnel on the real server as described in the docs.
i.e. # /sbin/modprobe ipip # ifconfig tunl0 0.0.0.0 up # ifconfig tunl0 192.168.1.176 netmask 255.255.255.255 broadcast 192.168.1.176 up AND make sure you sysctrls for ARP OR: echo 1 > /proc/sys/net/ipv4/ip_forward # insert it if it is compiled as module modprobe ipip ifconfig tunl0 0.0.0.0 up ipchains -A input -j REDIRECT 23 -d 172.26.20.110 23 -p tcp (IPs are just from cut and paste examples) I assume that TUN still can't be used in modern versions of Windows? 2009/3/19 Nelson Serafica <[email protected]> > > I already setup my rules in ipvsadm.
