  • Catalyst 3750, ASA 5510 and Sophos WS1100

    Hi !

    I'm experiecing issues installing the Web Security appliance from Sophos in explicit mode in a cisco network.
    Here is the problem :

    The 3750 send all traffic to ASA 5510. Putting the WS1100 in the pipe, how can I redirect only 80, 443 and 21 ports from 3750 to the appliance ?
    I should block these ports on the 5510 from 3750 and allow them only from WS1100. Don't know if I'm clear (i'm not very keen on Cisco and I'm French) !

    Thx for any idea, advice or help

    It seems to me that the default gateway on your client machines needs to be the WS1100 and the default gateway on the WS100 needs to be the ASA5510.

    But why do you have the WS1100 when the ASA5510 is a firewall?

      WS1100 is here as URL Filter.
      I tried to put ip address of the firewall as gateway but the appliance doesn't seem to accept it : i got "problem saving settings" !

        Well maybe you could call Sophos as I'm assuming you have support for the WS100, right?

        Otherwise you could try configuring things this way:

        client-->switch-->ASA5510-->WS1100
