I have Site-to-Site VPN connection between cisco router and series 3000 VPN concnetrator. After some time(it seems after Rekeying Phase 2) no data is passing IPSec tunnel. The tunel is up and the following error is reported on VPN concentrator (clinet ip is 22.214.171.124):
40963 06/12/2007 13:29:43.290 SEV=6 IPSEC/7 RPT=12295
