If you have an « NO PROPOSAL CHOSEN » error, check that the « Phase 2 » encryption algorithms are the 
same on each side of the VPN Tunnel. 
Check « Phase 1 » algorithms if you have this:

If you have an « INVALID ID INFORMATION » error, check if « Phase 2 » ID (local address and network 
address) is correct and match what is expected by the remote endpoint.  
Check also ID type (“Subnet address” and “Single address”). If network mask is not check, you are using a 
IPV4_ADDR type (and not a IPV4_SUBNET type). 
Check in ZyWALL SA monitor if a previous SA is still alive. 

Read logs of each VPN tunnel endpoint. IKE requests can be dropped by firewalls. An IPSec Client uses UDP 
port 500 and protocol ESP (protocol 50). 

If the VPN tunnel is up, but you still cannot ping the remote LAN, here are a few guidelines: 

•  Check Phase 2 settings: VPN Client address and Remote LAN address. Usually, VPN Client IP address 

should not belong to the remote LAN subnet  

•  Once VPN tunnel is up, packets are sent with ESP protocol. This protocol can be blocked by firewall. 

Check that every device between the client and the VPN server does accept ESP 

•  Check your VPN server logs. Packets can be dropped by one of its firewall rules.
