HI Auraza, the other side device is Cisco PIX with version 6.3(4). And here is the isakmp setting for the PIX:
isakmp policy 10 authentication pre-share
isakmp policy 10 encryption 3des
isakmp policy 10 hash sha
isakmp policy 10 group 2
isakmp policy 10 lifetime 86400
Concentrator IKE Session:
Encryption Algoritm: DES-56
Hashing Algorithm: MD5
Diffie-Hellman Group: Group 1
Auth. Mode: Pre-Shared Keys
Rekey Time Interval: 86400
Although I found the encryption, hashing and DH Group are different between them, but actually the connection can established for sometimes. Do you think the connection error messages are trigger by this? Please help.
