topic NAC Configuration in Network Security https://community.cisco.com/t5/network-security/nac-configuration/m-p/706934#M1054387 <P>I have a wireless network that is seen by the VPN 3000 concentrator as one IP address. If I have one person logged onto the vpn and then a second person tries to logon the vpn, the first person gets booted off with a reason 427 error. On the event log of the Cisco VPN concentrator I see an error of NAC is disabled for peer. It seems I cannot have more than person connect to the vpn that is coming from the same IP address. How do I configure my VPN Concentrator to allow for more than one client to connect if they are behind one IP address?</P> Fri, 21 Feb 2020 09:25:00 GMT rgobencion 2020-02-21T09:25:00Z NAC Configuration https://community.cisco.com/t5/network-security/nac-configuration/m-p/706934#M1054387 <P>I have a wireless network that is seen by the VPN 3000 concentrator as one IP address.
