HTTP via ADSL, the rest through DIGINET

[xsel]

Hi

I need to enable office web access through an ADSL modem.
The problem is that there is a diginet line connecting this satellite office to the main branch for email access to an exchange server.
Just turning off diginet and enabling all access through the ADSL modem is definately going to break everything(I checked with an exchange pro).
Thus I want to only enable web access through the adsl modem.
All pcs are dhcp enabled,and I see a gateway ip address.
I need web browsers to see another gateway(the adsl modem).
The exchange pro said "setup another gateway"
I see this as a problem as 1)I dont know how, and 2)how do the web access packets know they must only use the adsl modem gateway and not the diginet agetway?

I then had a bright moment and asked him about setting up a proxy server.
He said this sounded good,possibly better.
If I go with this option I can install FREEPROXY on one of the pc's,(ip is not static, a problem?)and point all pc's to this proxy and proxy points to static ip adsl modem.
Workable?

Thanx/Pete

Just point all workstations to use ADSL router as Default gateway.Change the DHCP server scope options , and change the default gateway assigned to all workstations from the diginet router to the adsl router

No, this will allow all traffic to the Internet to go through ADSL. He only wants browser traffic to go through ADSL.


Easiest would be to set your workstations' browsers to use a proxy server (For Internet Explorer: Tools > Internet Options > Connections > LAN Settings).
The proxy server should have 2 network cards (one for the internal network and the other for the ADSL router).

Don't use Windows' Internet Connection Sharing as this is not a proxy server - it's actually a software router.

You can use a Linux machine and Squid as the proxy server software (all this will be free). Alternatively, you could use your Freeproxy software - I haven't used that myself though.

Your gateway in TCP/IP settings for your workstations should still point to the Diginet router's IP address. The proxy server must have a static IP address for both network cards.

Hope that leads you into the right direction.

I have this same setup working at 4 clients already. Just a few questions before I put in my 2c worth.

1. Do the cients use any services over the diginet? File server, apps etc.

2. Is the branch firewalled? If so with what?

3 What router do you have connected to the diginet?

My 2c.

1. If the clients don't have any other services over the diginet just make the DSL the default gateway. Your branch exchange will still use the diginet as the Def. gateway so there mail wont break.

1.5 If you don't have a mail server in your branch just make the client default gateways the DSL router and make static routes, on the client PCs, for your remote email server using a gateway of the diginet router.

2. If the branch is firewalled just set the firewall as the defailt gateway and route HTTP protocol to the DSL router and everything else to the diginet router.

3. If you have a Cisco router connected to the diginet find out if there is a DSL interface made for it and it's price. You may be able to add a DSL interface and just route HTTP protocol out the second interface on the router.

There are anothe 10 way I can think of doing this but we really need more info on the environment. Good luck.

Ya didnt read his question right.Keep default gateway to diginet and setup HTTP proxy.The HTTP Proxy's default gateway will be the ADSL router
