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?
