IPsec site-to-site support
Actually NethServer support site to site VPNs only with OpenVPN protocol, it's important to extend this possibility also to IPsec protocol.
The main goal of this add is to increase the interoperability with 3rd parties firewalls, but is also welcome as futher option for site to site connection beetween 2 nethservers.
It's necessary a dedicated tab to make all configurations (IKE/ESP tipe, integrity and so on), we can refer to many different opensource products like ipcop or endian firewall for the parameters needed.
Probably the account tab can still be used (e.g. for a site to site VPN beetween nethservers) , but something is needed to choose the vpn type (OpenVPN or IPsec, maybe a checkbox?)
