3 Network Cards in ISA Server 2006

Hello,

I have ISA Server 2006 in Production.
Config.
Internal Network : 192.168.10.0 255.255.255.0 [Internal LAN]
External Network: 212.xxx.xxx.xxx [Leased Line] [This NIC has the gateway and DNS]
Used for VPN, Outlook Web Publishing,Proxy and also allows SMTP traffic.

The ISA Server box has 3rd network card which I want to use for Internet Browsing [We have seperate high speed connection from different ISP]. Reason being, interent browsing will not hog all the leased line and yet do the web filtering.

Can I just configure it with one of the INTERNAL IP addresses ?
If YES then
What about gateway and DNS Server ???
Also, I understand that I will have to configure the access rules for HTTP and HTTPS to go from InternetBrowsing [3rd NIC].

Any advice / better idea is welcome.

Extra Info. [I do have couple of internet facing IP add. from the ISP for the 3rd NIC OR I can make it sit behind a Draytek router with an internal IP, this is where I am confused. ]

Thanks
RC

Hi there,

Right just to be sure I have got your question, You have 2 lines with internet access you want to keep one dedicated for VPN... OWA atc..

This is something you cannot do via ISA. You will need to look at geting a dual wan router with either load balancing or traffic shaping. and will give you something hat would look like this

----------- Net1 ------ Modem1 ----- Wan Port 1
                                                   Dual Wan Router ---------- ISA ----------- Internal
----------- Net1 ------ Modem2 ----- Wan Port 2

In short the 3rd NIC card would only be useful for a DMZ on the ISA box.

Regards
Steve
