recently I installed OpenVPN to my WD MyBook Live. Basically it works very well, I can access the MyBook remotely via the tun/tap devices.
Next step should be to add a route to my private LAN. Sadly OpenVPN wont let me ping the pc's in my LAN.
My guess is, maybe there are some firewalling / iptables issues, but everytime I try to list or edit the iptables chains, the MyBook just throws me this exception:
FATAL: Module ip_tables not found.
iptables v1.4.2: can't initialize iptables table ‘filter’: Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
is there any way to get iptables working correctly on the MyBook Live?
For the record, IP-forwarding is enabled via /proc/sys/net/ipv4/ip_forwarding
