Hey everyone!


I'm running Vista RC2 at the moment, which is lovely. However, is it possible to route all internet/external connections to one NIC? I have two at the moment, both on internet featured networks, and i'd like to route everything internet-based to one, so I can have the other for local-only activities.

Any ideas?

Cheers,
Oli

you may be able to use the "route add" command in command prompt to do this...

open a command prompt and type route /? for the syntax

basically you'd want to make a static route (persistant if possible) that would point all traffic for 0.0.0.0 mask 255.255.255.255 Edit: the actuall netmask for this theory should be 0.0.0.0 meaning...all networks...a netmask of 255.255.255.255 would exclude all but one ip address (i.e. 192.168.0.1 with a subnetmask of 255.255.255.255 would mean ONLY the ip 192.168.0.1 is part of this network)..sorry for the mistake :whistling: to the internet NIC....this SHOULD route all Internet traffic out of that NIC

Would that not point all traffic to an IP though?

I just thought that setting a net mask of 255.255.255.255 just redirected everything, maybe I'm wrong!

Set it at the router level. Have one NIC blocked off from the external WAN.

Thanks for the suggestion! I must have skipped past the option about 5 times, but I discovered the DENY_OUTBOUND variable on my rc.firewall script .. So all is well in the household now :]

Thanks a lot for the help guys!

just as a note on the route that i suggested...it would route all traffic...but only ALL traffic destined for an unknown network (i.e. the internet) not neccessarily all traffic internally...because you SHOULD have routes in place for the two internal networks (as they're added by default) also...technically you should have at least one route already in place for 0.0.0.0.... but...you've solved the issue so...there you go!

Ah fantastic! We'll I will remember that for the future! I have heard about the routing program in Windows, but never knew what use it was for .. So thanks a lot for the information on that one!
