So.. it would know which NIC to route it to? 192.168.0 will go through eth2 automatically. what if I want to go to www.hotmail.com? > > > > > You default gateway would have to be reachable by either > one of those devices as determined by the ip address and the subnet mask. > since one is company network and the other is internet,(wifi) they cannot go through the same gw. They are not routeable between each other. company Lan will not talk to internet.

Ah..solution to my problem. Say I want to go to www.hotmail.com, so, the packets will need to go through the 192.168.0 NIC(->wifi->DNS->NAT->Inet etc) to get there right? > > > > for example, company also has a remote office in Timbuktu which has a > > network of 192.168.1.0 subnet mask 255.255.255.0 - this network is > > already tied into your existing network through a vpn/router > > scheme and you want to reach the server at 192.168.1.5 > > > > Since 192.168.1.5 isn't reachable with either of your network/subnet > > mask configurations, any attempts to ping/contact > 192.168.1.5 will go out to your default gateway (that's why it's a default gateway). > > > > So to route your packets for 192.168.1.0 network through the company > > router, you would need to know that ip address (i.e. > > 192.168.0.254) and THEN you would have enough info to set up a static route... > > > > route add -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.0.254 dev eth2 I can't do a route add -net (ip of www.hotmail.com) netmask 255.255.255.0 gw (GW of www.hotmail.com) dev eth2 That can't be right, right? In a nutshell 10.0.0.10 -> gw 10.0.0.1 (company lan) eth1 192.168.0.1 -> gw 192.168.0.10 (wifi/nat/internet) eth2 So I want to go to http://intranet.company.com (ip add is 10.0.0.3), the packets will go through eth1, through the default gw of 10.0.0.1 and reach the intranet if I want to go to http://www/hotmail.com how does the packets get there? assuming of course that lan is for lan traffic only. Cannot access Internet _at_all_ I hope you understand what I'm referring to.. I's kinda hard for me to describe.
