Has anyone gotten the Cisco VPN client to work with a Contivity? I have a group of users that are requesting this and I can't get it to work. The contivity is set to allow non-contivity clients and I have verified the config with Nortel. According to them it appears to be a negotiation failure as the logs are showing "no proposal choosen". I tried disabling all encryption except 56-bit. We disable compression, perfect forward secrecy and anti-replay as well.
