Greetings....

Well want to remove gateway & dns at client end my current scenario is

I ve two servers and one dhcp server that assisgn ips to client along with the their repective gateway of client using mac based authentication dhcp header file caintain normal dhcp configuration while dhcp body having the congfiguration for both gateway and dsn .

Since my both gateway has independ they both have their own clients running,so it could be possible to acheive that task cause I will let dhcp to assign just ip and subnet to clients and remove gateway n dns part from there . I using squid in transparent mode for proxy . how to accomplish this I've seen this senerio on ISA 2000 one is dhcp server that assign ips to client and clients have isa client installed that have gateway ip which help the user for carrying http request and other in same way we have squid running in transparent mode . hope you guys got my point .

Sorry, I cannot understand your question.

Maybe you can rewrite this, if you still need help?

Just configure the dhcp server to not provide a gateway address to those clients, or to provide them with a null address. Of course, you could also remove the dhcp client from those two machines and use other means to assign them IP addresses (such as using fixed IP addresses) and to provide them with dns server addresses (such as an openresolv script).

I'm not sure I understand your use of the term "transparent", but you could also use a firewall on the gateway (or between the clients and the gateway) to block layer-2 communication between them. Then they wouldn't be able to "see" the gateway.

Hi,

I'm also not quite sure, if i understand you correctly...but

Set up the proxy in the local subnet (non-transparent!!). And enter the IP as Proxy in the browser! that's it!

That way you don't need a default gateway and dns entries on the clients...
But that will only work for protocols that can be proxied!!!
And only do that, if you have just one local subnet!

---The ISA-client is imho a really bad hack, which bends the tcp/ip stack of the client!

Cheers!
