control Internet access in virtual community

Specs: Windows XP

I have to setup a way to control Internet access to eliminate/reduce abuse, and all the side effects like bugs and worms.

The entire system is set up in a virtual community, and I have NO access to router(s)

all are on a fixed IP,

we have a SCSI server on UNIX. ip=1

we have axel tcp/ip terminals, esprit400 dumb terminals, port servers, and dot matrix printers rs/232.

we also have quite a few PC's, all on XP pro, mixed into the lot. They work with term emulators for the Unix server, as well as accessing internet for catalogs, email, and researches.

what I want to do, is set up a 2nd network adapter on a PC, with the original adapter remaining in the network, and the second card to a smart-switch where I want to connect (move) all the PC's, putting the pc between the other network pc's and the rest of the network, including Internet access.

then, with something like ccproxy, limit/filter Internet access, while giving access to the rest of the network

on a test pc, I have set this up, and as soon as I activate the new card, all network is lost. It comes back when I disable the new card.

I have the ip 5 on the net adapter, and 6 for the new one to the switch. (I have ip 9 on a pc to the same switch to test)

If i bridge the adapters, anyone can bypass the proxy.

I lose it all with both adapters connected. I am trying to figure a way to take from adaptor B, monitor with ccproxy, and pass on through adaptor A.

i am now royally stuck

Only one ip address can have a gateway entry. I suspect you have multiple gateways listed which does not work.
This is assuming you are not dealing with a hardware conflict concerning the nics

I have no conflict or error for the nics

ip 5 has a gateway to the Router, and Internet.
I have ip 6 with a gateway to 5.

so, if I understand correctly, the card with all PC's should have no gateway.

I will try this right away, thanks, and BRB!

I removed ip 6's gateway, AND both dns server addresses.

My test PC (ip 5) can now access, internet with both nic's on, can also get emails, but can not logon to ip 1, the unix server.

ip 9 can ping ip 6.

test pc can ping itself on ip 5 and ip 6

test pc can ping ip 9
test pc cannot ping the rest of the network

I do believe i will, at this point, bridge both nic's, and do a bit more r&d.

thanks anyways, and I will come back when I have advanced a bit more

Thanks for your time
