Can WiP-500+ work with Cisco Systems VPN client software ?
Clearly that depends on the version and revision of their software. And the particular features they offer. So it is best to ask Cisco for help with their software. However from our experience the WiP-500+ ipsec passthrough feature will work with the Cisco ipsec client. WiP-500+ should work with any ipsec client which supports ipsec NAT traversal feature. For the IPsec server side please discuss with your local network support expert and your software provider.
