First of all let me admit that i m novice to this technololgy of VPN's & FW's so you may expect all types of silly doubts and questions from my end.
This is in regards to SITE-to-SITE VPN between two offices both on ADSL connection. I was somehow able to fix the VPN between to offices.
It worked for couple of days but later the tunnel went down and it is still down I think when the public IP address changes it is not updated to the hostname registered with DDNS. I have mentioned the configuration in the attached file
Earlier Qlemo suggested me few things to do such as
Clear ike-coo all
enable VPN monitor etc.. It started all working fine but not for very long.
please suggest me if there is anything i am missing for the VPN's to stay stable.
Thanks in advace,
