Network to Network IPSec VPN using RHEL/CentOS: separate VPNRouter and LAN Gateway Hmm I'm not in IPSEC, I'm using openvpn and in my opinion it's easier to setup and maintain. If you want to connect just two private nets it would be very easy to do with openvpn. Regards Darek ... 13 May 2010 17:08

Network to Network IPSec VPN using RHEL/CentOS: separate VPN Router and LAN Gateway Hi there, I followed the RHEL documentation at http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-vpn.html and was able to deploy network to network IPSec VPN between two private networks, as long as I set the IPSec Routers to be the same as the LAN gateways. But according to the documentation, it is... 6 May 2010 23:08

Every now and then, these boxes lose contact with the network: we find ... 5 May 2010 16:01
