IF you are not stuck to IPSec, you might want to take a look at OpenVPN (www.openvpn.org). I found OpenVPN easier to install than FreeSWAN (an IPSEC VPN) and have setup an OpenVPN solution between my German office and our mainoffice in a matter of hours.

On the first location we have a cisco pix 525 Natting the internal 192.168.100.x network, while on the second location we have a Centos3 box Natting via iptables the internal 192.168.10.x netowrk. My goal is to connect this 2 over the internet via IPsec. I created the IPsec Net2Net via the network configuration graphic tool, and I configured the cisco following the howto http://www.johnleach.co.uk/documents/freeswan-pix/freeswan-pix.html . From my understanding, I should have an ipsec0 network device showing up, so that I could route all traffic from 192.168.10.x directed to 192.168.100.x through it. The thing is that when I try to ifup ipsec0 I get the following errors: modprobe: modprobe: Can't locate module ripemd160 modprobe: modprobe: Can't locate module cast128 modprobe: modprobe: Can't locate module lzs modprobe: modprobe: Can't locate module lzjh So, after googling and reading a lot with no success, I would like to ask for advice on this, and successfull story :). I really need to have this VPN running, and I am not tied to this one solution only, linux-to-linux VPN, openVPN or anything else you could suggest would be great. Thanks in advice Simone _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos -------------- next part -------------- A non-text attachment was scrubbed...
