I have a Zyxel USG 100, and I am tring to setup a VPN.

My local network is : 192.168.0.0/24 Gateway 192.168.0.1 NETWORKA There is another network 192.168.1.0/24 with Gateway 192.168.1.1 NETWORKB I can access to both without problems on this network my ip is : 192.168.0.10/24 Gateway 192.168.0.1

My remote network is 192.168.10.0/24 gateway 192.168.10.1 NETWORKC

There is a l2tpVPN/IPSEC to access to it and it's working fine ( VPN : 192.168.11.0/24)

After the connection I got the ip : 192.168.11.0/24 Gateway : 0.0.0.0 I can access to everything on the remote (NETWORC), to my local NETWORK ( NETWORKA) but I lost access to NETWORKB.


NETWORKC  FW-------------------------FW------NETWORKA

                                                               ------NETWORKB

Any idea where is the problem and how can i fix it ?

Thanks a lot

    192.168.10.0/24-----(LAN)USG100-----Internet-----USG100(LAN1)----192.168.0.0/24
                                                                                                 (LAN2)----192.168.1.0/24

    Is site to site VPN configured between two USG100?
    Where is L2TP VPN client located? Which USG100 does this L2TP VPN client connect?

    Best regards,
