I have two road warriors that have broadband and are able to connect to the vpn with virtually no problems but when a third user who has a verizon card trys to connect it won't allow him to connect, unless i clear the crypto isakmp. Then he is able to connect but then the other users are not. I turned on debug to see what going on. can someone help!

Hi Eddie,

Issue command sh ver and check if you have enough VPN peer license.

I suggest you to upgrade your IOS to 6.3(5) first. Second, make sure you have isakmp nat-traversal 20 issued in config
