I'm able to get the tunnel to establish but am getting the following error:
4 Sep 17 2007 03:31:32 402116 126.96.36.199 188.8.131.52 IPSEC: Received an ESP packet (SPI= 0x57FB960B, sequence number= 0x25) from 184.108.40.206 (user= 220.127.116.11) to 18.104.22.168. The decapsulated inner packet doesn't match the negotiated policy in the SA. The packet specifies its destination as 22.214.171.124, its source as 126.96.36.199, and its protocol as 1. The SA specifies its local proxy as 10.2.0.0/255.255.0.0/0/0 and its remote_proxy as 172.16.32.0/255.255.255.0/0/0.
I can ping from the Cisco side to the Netscreen side, but in the reverse. The Netscreen reports the tunnel being inactive.
Are there any interoperability issue here? What can I do to make this work?
