Title: IPSec problem between DFL-260 and DFL-800
Post by: maryam on August 07, 2010, 04:34:27 AM
Hi,

I have set a lan-to-lan IPSec tunnel between two DFLs based on the configuration file from D-link. After the IPSec tunnel is established, it remains working for about 24 hours, more or less. When IPSec drops, I can ping the remote gateway and and even connect to remote firewall GUI console, but in IPSec IKE Status section shows  "Encryption Algorithm Unknown". Is there any specific configuration required for solving this problem?

Thanks,
Maryam

Ensure things are the same on both sides, particularly lifetimes.  There is not much more to this.
