The users are behind a Microsoft ISA 2000 firewall which is doing NAT overloading. The problem is only one user can connect the VPN box at a time. If the second user try to connect the concentrator generates a log like "access denied: connection already estabshiled with the remote peer (remote IP)".</P><P></P><P>Here is the network diagram</P><P></P><P>Users ----&gt; ISA server (NAT overloading) ----&gt; Concentrator.</P><P></P><P>All users are using Micosoft DUN for their PPTP connection.</P><P>How can I fix this problem????</P><P></P><P>~/Dev </P> Fri, 21 Feb 2020 08:01:13 GMT https://community.cisco.com/t5/network-security/pptp-vpn-problem/m-p/333724#M1056416 somudrodev 2020-02-21T08:01:13Z Re: PPTP VPN problem https://community.cisco.com/t5/network-security/pptp-vpn-problem/m-p/333725#M1056417 <HTML><HEAD></HEAD><BODY><P>Your Nat overloading is not functioning properly; the clients are suppoesed to go with the same IP and they are not</P></BODY></HTML> Tue, 22 Mar 2005 20:53:51 GMT https://community.cisco.com/t5/network-security/pptp-vpn-problem/m-p/333725#M1056417 umedryk 2005-03-22T20:53:51Z
