    Is my lan secure?

    jcmiller54

      Hello,

       

      I am running an SG560 Ver. 4.0.7

       

      I've recently had to change up my ISP. I currently have this setup.

       

      A1 - Lan - DHCP Server - 192.168.99.x (Has a wireless access point connected. DHCP by SG560.)

      A2 - Unused (Had been a guest wireless connection that kept giving me grief with disconnects.)

      A3 - Unused

      A4 - Internet - ADSL PPPoE (runs about 300k)

      B - Internet - Wireless Hub

       

      The internet connection to the lan is working well. I'm concerned about wireless connections to the Wireless hub, which is running DHCP - 192.168.1.x

       

      I want to keep wireless clients from accessing the lan through the wirless hub.

       

      Thanks

      John

          Setup the wireless connections of port A3 which you would configure as a DMZ.....which will restrict access to all but the internet

            Hi Ross,

             

            Not sure if I made myself clear. The wireless hub provides me with internet access, and can also act as a wireless access point. I was thinking that I might be able to use it as a guest wireless point.

             

            If I plug that into A3, I need the lan to have internet access through it.

             

            If I use it as a wireless access point, can I limit it's access to the lan?

             

            Would I be better to turn off the the wireless in it, and connect a separate acess point to A3?

             

            Thanks

              yes you are correct.....seperate wireless AP on port A3

               

              I was assuming you had a seperate wireless access point to use for this...

                Thanks,

                 

                With the WAP on A3, would the SG560 look after DHCP, or should the WAP have DHCP turned on?

                 

                If some of my questions don't make a lot of sense, please excuse me. I really don't have a clue how this stuff works, and am always surprised when I actually get it functioning. Speaks volumes for the ease of setup with the SG560.

                 

                Regards

                  you can use either dhcp server....but not both !

                   

                  usually easier to manage in just one place....so I would do it on the SG560 if it was me.
