Hello,

Is it possible to have two different gateways to
Internet in a flat network?. We have static IP
addresses for all the computers on the
network, and now we've decided to use a
second ISP for certain tasks like VoIP and
videoconferencing. Can I just assign an IP and
plug the second router to the switch, and then
use it as the gateway for some clients?

I have the 192.168.1.1 (firewall IP, default
gateway)

Client: 192.168.1.20 / 255.255.255.0
GW: 192.168.1.1
DNS The ISP DNSs

Second router, i.e 192.168.1.100

Client: 192.168.1.30 / 255.255.255.0
GW: 192.168.1.100
DNS: The second ISP DNSs

Would it work right away?

Thank you very much,

Jud

"then use it as the gateway for some clients?"

Thanks wanderer, I'll try it tomorrow !

I also plan to add a Windows Small Business 2008 server, do you know if I'll have problems to use this dual gateway configuration?.

Have a nice day,

Jud
