In my office network, There are some rules on ports and site access for our network. To access restricted sites and make connection through restricted ports, I had connected a 3G Modem card on my computer. When I connect with the 3G Modem card, all my connections are done through it. Everything was OK. But By this time, I lost connection from local area network, and I couldnt access IPs on my local network. I had edited the etc/hosts file like:
10.222.2.176 ADRESS1
10.222.2.178 ADRESS2
10.80.3.17 ADDRESS3...
... and so on. so, I was able to reach those addresses. because, for some reason, my comuper find the right server on 10.x.x.x network ( Local Area ). But I couldn't spoof my outlook to make connection to exchange server which has a domain name like a.b.com.tr ( and IP of 10.x.x.x ) So, When I connect with 3G Modem Card, I was disconnected from Exchange and Office Communicator which I dont want.
What is the rigth way to route the traffic between the Local Area and 3G Modem Card Connection. If this is impossible, At Least, It's OK for me to just make 3389 connections from 3Gmodem Card, and other all connections from Ethernet ( Local Area ) Card. Or How can we set rules based on ports acrross these connections.

for SysExpert: We can not change any setting in our DNSs or ISPs. 3G Modem Card Dial Up connection is a GSM Operator's network for internet access, The LAN connection is a secure network of our office which we can not manage anything. The exact question is: I want to make TCP 3389 connections through 3G Modem Card ( Dial Up ) and other connections through LAN when both of my connections are connected ( active ). How it set in XP. Is there any routing software which manages these routing rules for window xp pro. Is there any software which acts before the native network interface behaviour occurs.
Thanks for your tip SysExpert. The route command worked.

My LAN gateway address was 10.222.2.222, and my Local area network was all 10.x.x.x subnet.
son, I command prompted > route add 10.0.0.0 mask 255.0.0.0 10.222.2.222
everthing works like I expected now. the documentation says, put -p for persistence to registry like
> route -p add 10.0.0.0 mask 255.0.0.0 10.222.2.222
And also, make the HKEY_LOCAL_MACHINE\SYSTEM\
key 1 on registry to enable xp routing.
Now, when both dial up and LAN connection is active, my all 10.x.x.x requests goes through LAN, and other requests my XP behanves native. So, I go to internet with my 3G Modem Card, and also I am in my local area network. It's great for the freedom :)

you can use the interface metric (network properties, interface {lan or dialup}, tcpip properties, advanced, interface metric) to determine the order of interfaces to route to i.e LAN can be 1 and dial-up 2, this way all traffic is routed to lan unless host is not on your lan.
