Hi,

What is 203.200.xxx.xxx address. Looks like your VPN Server is sending UDP Port 500 packets to the remote 203.200.xxx.xxx and not getting any kind of response. Do you know if UDP Port 500 is blocked on the remote side.

Do you have a copy of the configurations from both the VPN Servers.

Regards,

Arul

*Pls rate if it helps*
