Hello everybody,

I try to setup communication between IPSEC VPN clients on Zywall 310. Clients can connect and ping LAN interface, but can’t ping each other.

My setup:

Zywall 310



Users are using Shrew VPN client to connect. Client’s IPs are static from subnet

Policy Generation Level: required
Remote Network Resources:,


Can anybody help me to find right configuration?


Thank you.

    I also got the same problem when using ZyWALL IPSec VPN client. :/
    Use mode config on both ZyWALL and ZyWALL IPSec VPN client but clients cannot ping each other.

    VPN Connection:

    Scenario: Server role

    Local Policy:
