We have cisco pix at our office and remote user using cisco pix client for remote login. But we are using 192.168.1.0 network on our office and this days most broadband router using 192.168.1.0 network. most of users trying to connect out side office from broadband they can connect but cant' access to mail server and all other servers because of that same ip network . I have changed one users broadband ip from 192.168.1.0 to 172.168 network and it works fine but it is not possible for all users. Is there any option ?
