I have been instructed to throw out old firewall set up by external company and install a Cyberoam unit. I have deployed the solution in gateway mode. Current firewall is not managed by myself and the company managing it is not very forthcoming with the info. I inhereited the site and need to secure it asap. I am by no means a network specialist but I am also not a complete idiot. I would appreciate any help in setting up the following scenario.
Users must VPN in with the client provided by Cyberoam appliance using either a preshared key or a certificate. I can manage to set up the connection just fine, but I have to specify a different ip range to be distributed to people connecting via SSL VPN. I need to have the people logging in to have a IP assigned by either my DHCP server or a range within my internal range so they can access all internal servers and shared drives.
Internal range is 172.22.109.xxx but when I try to add the address range I get an error saying the internal range is already in use and I need to specify a differnet range. When I use 192.168.1.xxx I can connect successfully, but cannot access any internal resources because I am on a different ip range. Please point me in any direction as to what needs to be done to get this working.
The current VPN connection works with openvpn and the people connecting has access to internal network through ip's assigned to internal range. I have no idea how they set it up.
