Hi,
I got problem to integrate ZYXEL VPN (Zywall 70) to our network that using Layer 3 switch (cisco 3560). Seems the Zywall only able to do tunning between LAN to LAN but unable do LAN to LAN to routing LAN.
I succeed to configure and the secure tunnel was created and run well. But when I tried to route into internal subnets, it always RTO (unreachable) and from internal subnets unreachable the remote, as well.
Your advise & comment is very apprecited. Thank you very much for your kind help.
Best regards,
Awie
