You will have problems if you change the Rulebase to use 3DES before the
SecuRemote clients are upgraded. The reason for this is that 3DES-capable
software can encrypt or decrypt using DES, but DES-only software will NEVER
decrypt 3DES-encrypted data.
Thus, you should do the upgrades in the following order:
1: Upgrade the firewall software to 3DES, without changing the encryption
algorithms from DES to 3DES.
2: Install/upgrade SecuRemote to 3DES-capable version
3: Change the encryption properties in rules to use 3DES.
Note that you may not be able to specify 3DES unless the license features in
the management station include strong encryption.
