Hi,

did you reboot after editing /etc/sysctl.conf.

Alternatively you could try:

Code:

cat /proc/sys/net/ipv4/ip_forward echo "1"

(no need to reboot for changes taking effect).

You could also stop iptables during troubleshooting (so you don't have to worry about firewall misconfiguration).

Also, please share the output of:

Code:

route -vn

(make sure the default gateway is 10.10.10.254).

see ya
