Zywall 310 L2TP Over IPSec Destroying tunnel due to no connectivity to its peer within 121 secs

Peter_Koreshkov · October 30

Trying to connect from Windows 10 using l2tp.

IKE log says: Dynamic Tunnel [Default_L2TP_VPN_GW:Default_L2TP_VPN_Connection:0x3df3aee6] built successfully

35 sec later: ISAKMP SA [Default_L2TP_VPN_GW] is disconnected

L2TP log (35+121 secs later): Destroying tunnel ID 11812 due to no connectivity to its peer within 121 seconds

Windows client log say RasClient error 809 (id20227)

Packet session looks like no answer from Zyxel (176.114.*.*)

Please help me to understand, whats wrong

HI @Peter_Koreshkov ,

Please be aware that the Zywall 310 model has reached its End of Life (EOL) status, which means our support for this model will be limited. You can try the latest weekly firmware (version 4.73-23WK36) that is sent to your Community inbox via private message.

For optimal performance and support, we recommend exploring our current firewall offerings here:
