BZ Kerio 2x Default Replacement Update - Interpretations Help. Hi, I am looking for help deciding which DHCP rules to use, or if they are necessary at all. I have a XP SP2 laptop which is currently connecting to a DLink 624 router via cable. The router is connected to a ADSL modem. My laptop receives its IP address automatically. There's also a XP Home SP2 desktop that connects to the router but that machine shouldn't figure (has its Sygate). I am asking for help because the laptop couldn't get to the Net after setting up Kerio 2.1.5. I followed BZ Kerio 2x Default Replacement Ruleset with DHCP being on the top row of the list. Thanks a lot for your help.
