Symptom:

192.168.8.0/24 can’t access 192.168.9.0/24

Checking:

1)The policy of Any to ZyWALL have allowed ESP service and also allow AH if you it. Please ensure there are no deny rules above it.

2)VPN -> IPSec VPN -> VPN Connection , please check you have set zone. If you have customize zone, please remember to add additional security policy.

3)If the above doesn’t help, please try replacing ESP to AH and contact Zyxel Support for further investigation.
