I have ISA Server 2006 in Production.
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. ]
