![]() Just to answer your question, I tried it with the Mac OS firewall off, and it doesn't work anyway. When I issue the "netstat -r" command in both Mac OS and in Windows, the routing tables look almost identical in that every network in the above ACL is installed into the routing table and the next hop for these networks points to the OS's interface connected to the Internet. I have no problem connecting to an EasyVPN server configured this way and communicating with any networks specified in the ACL called from within the "crypto isakmp client configuration group". I use an EasyVPN-like configuration except for I use a route-map and a dynamic route-map instead of virtual templates. ![]() I have configured a Remote Access VPN many times on Cisco routers, using CLI. From the same MAC, when I launch a VM with Windows, and connect to UC560 using the Cisco VPN Client software, I can communiate with hosts on any of the four networks listed above. However, when I tried to manually configure a Mac (Mac OS X Lion) to connect to the UC560 via IPSec VPN, Mac OS connects, but I can only communicate with the subnet listed in ACE configured first in the ACL called from within "crypto isakmp client configuraiton group EZVPN_GROUP_1".įrom a Mac located on the Internet, I can only communicate with hosts on 192.168.101.0/24. ![]() pcf file into a Cisco VPN client (for Windows). pcf file, using CCA, and then imported the. At this point, UC560 is in production as a router/firewall/EasyVPN server (I have not yet configured the voice portion of it). To comply with the Cisco Small Business Pro requirements, I had to factory-default the UC560 and start the configuration from scratch. My hope is for my client's network administrator to use Cisco Small Business Pro support to take care of any support issues should they arise in the future. Because I am installing this for my client, I do not want to be involved in the support in the future. I had to use CCA because Cisco Small Business Pro support informed me that the entire configuration had to be done in CCA in order for Cisco to support the system. When the IPSec client initiates the VPN tunnel connection, the IPSec server pushes the IPSec policies to the IPSec client and creates the corresponding VPN tunnel connection.I configured EasyVPN on UC560, using CCA. Network extension mode allows users at the central site (where the VPN 3000 series concentrator is located) to access network resources on the client site.Īfter the IPSec server has been configured, a VPN connection can be created with minimal configuration on an IPSec client, such as a supported Cisco 870 series access router. Resources at the client site are unavailable to the central site. Client mode is the default configuration and allows only devices at the client site to access resources at the central site. The Cisco Easy VPN client feature can be configured in one of two modes-client mode or network extension mode. Easy VPN server-enabled devices allow remote routers to act as Easy VPN Remote nodes. This protocol allows most VPN parameters, such as internal IP addresses, internal subnet masks, DHCP server addresses, WINS server addresses, and split-tunneling flags, to be defined at a VPN server, such as a Cisco VPN 3000 series concentrator that is acting as an IPSec server.Īn Easy VPN server-enabled device can terminate VPN tunnels initiated by mobile and remote workers who are running Cisco Easy VPN Remote software on PCs. The Cisco Easy VPN client feature eliminates much of the tedious configuration work by implementing the Cisco Unity Client protocol. Figure 6-1 shows a typical deployment scenario. The example in this chapter illustrates the configuration of a remote access VPN that uses the Cisco Easy VPN and an IPSec tunnel to configure and secure the connection between the remote client and the corporate network. Remote access VPNs are used by remote clients to log in to a corporate network. Site-to-site VPNs are used to connect branch offices to corporate offices, for example. Two types of VPNs are supported-site-to-site and remote access. The Cisco 870 series routers support the creation of Virtual Private Networks (VPNs).Ĭisco routers and other broadband devices provide high-performance connections to the Internet, but many applications also require the security of VPN connections which perform a high level of authentication and which encrypt the data between two particular endpoints.
