I have visit following threads: https://www.wilderssecurity.com/showthread.php?t=176589 https://www.wilderssecurity.com/showthread.php?t=171678 but still something strange. I have using LNS 2.05p3 for long time, and new to 2.06. Phant0m v6 ruleset. (with some modify by me) VMWare Workstation 6.0 running in Bridge mode, Inside VM, I install offical XP SP2 with latest updates. Host PC LAN IP is 192.168.1.2 Guest PC (VM) LAN IP is 192.168.1.200 LNS 2.06 is installed inside VM. My problem is LNS 2.06 don't understand my LAN IP. In "Welcome" page, it show 192.168.1.200, not connected. no matter how I setting "IP to exclude" in Options -> Advanced options. (I don't test LNS 2.05p3 inside VMWare 6.0) Due to above problem, LNS cause following strange wrong: 1. can't connect LAN. (block) 2. can't connect internet (block, show ETH packet) Here is my resolved, but maybe cause security leak?? I manual add a rule in top of other rules. Rule Name: VM Source PC ethernet address: "Equip my @" (right-hand show correct MAC address of VM-NIC) select In/Out bound others setting are "ALL" after add above rule, ALL strange problem are gone. LAN has connected. Can connect internet, LNS 2.06 will automatic switch NIC from VM-NIC to "WAN miniport (IP)" but my rule are ok?? i don't know.
