This might be a routing issue or a firewall/NAT issue. Can you ping the gateway from the client? Did you try to use "Enable Transparent Tunneling"? The Cisco VPN client then uses UDP (port 4500) to allow transport through a NAT device.</P><P></P><P>Hope this helps</P><P></P><P>Martin</P></BODY></HTML> Thu, 15 Dec 2005 07:33:02 GMT https://community.cisco.com/t5/network-security/vpn-error-message/m-p/440819#M1055545 mheusinger 2005-12-15T07:33:02Z Re: VPN error message https://community.cisco.com/t5/network-security/vpn-error-message/m-p/440820#M1055546 <HTML><HEAD></HEAD><BODY><P>Check your connection, make sure you are able to ping the gateway from the router, and you can ping an address on the internet.</P><P></P><P></P></BODY></HTML> Wed, 14 Jun 2006 14:59:15 GMT https://community.cisco.com/t5/network-security/vpn-error-message/m-p/440820#M1055546 bensonomuke 2006-06-14T14:59:15Z
