I want to block other NAT that are behind my firewall (ex: wingate,
Microsoft ICS...), Someone know how to do it?
---Gateway-------|Client1
|
|Client2
|
|Client3|---|Sub Client1
|
|Sub Client2
Gateway = Linux 2.4.18 + IPTABLES + NAT + Squid
Client1 and Client2 = Windows 9x
Client3 = Windows 98 SE + ICS (Internet Conection Sharing (Microsoft NAT))
Sub Clients = Windows Workstations
My intention is to block the "Sub-Client1" and any other that is not
masqueradim by my own Firewall.
I have the MAC Adress of all masqueraded clients that I would like to permit
Thank you for the attention.
