Folks, Nevermind the below message. I found out how to enable ipsec behind nat on CCO. Problem fixed. Thanks. -Frank ---------- Forwarded message ---------- Date: Wed, 30 May 2001 07:46:59 -0400 From: Frank Kim To: [EMAIL PROTECTED] Subject: VPN to Cisco3030 concentrator behind nat [7:6405] Hi all, I got a pc sitting behind a cisco4000. The cisco4000 runs nat with 192.168.1.0/24 for the inside network. I am trying to establish a vpn connection to a cisco3030 concentrator with no success. I replaced the cisco4000 with a linuxbox running 'iptables' and it worked fine. What am I missing? Thanks for any advice. -Frank FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=6406&t=6405 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
