L2TP VPN for USG40 not working IOS
I have followed many configuration guides but have not solved the problem. I need to connect IOS mobile devices (versions 12 and 13) to the zyxel USG40 connected via WAN to a modem / router.
1) Create VPN User (Object / User tab)
2) Create WAN, L2TP_POOL and LAN addresses accordingly (L2TP range TO BE completely outside any home / external IP range, that might be in use in either end of the VPN tunnel during VPN utilization - otherwise you may expect trouble ...)
3) Create IPSEC VPN gateway
4) Create VPN connection that uses above created VPN gateway (you can utilize default available or create own)
5) Create L2TP VPN
Is it possible to receive a correct guide to configure the l2tp connection for mobile devices?
