Re: [FW-1] NG to Cisco router VPN setup.



sounds like phase I went ok and you need to look at phase II.  "no proposal
chosen" usually means that the 2 sides do not agree on the encryption
scheme.  for instance, one side might be trying to do esp-3des-md5 and the
other esp-3des-sha.

hope this helps
