Hi, I setup static for remote connection now for rdp. I want to know what advantage is setup the remote VPN client on pix.

the main benefit is to secure the connection.

providing port forwarding and inbound acl have been configured for remote user, all the traffic is traversed in clear text.

the remote vpn client needs to be installed on the remote pc.

Hi, is there another remote VPN method? My friend don't need install VPN client.

Re: Remote VPN

jackko — Mon, 09 Jan 2006 00:14:20 GMT

not with the pix501. with pix 515e or above, webvpn would the other option.

just wondering what sort of device your friend has. it may be feasible to configure a lan-lan vpn between you and your friend.
