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 Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=6405&t=6405 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
