Multiple routing cisco 877w

Hi,

i need help, i have a cisco 1840 conected to internet with a 10.10.10.0/24 sharing valid ip address, in the other hand a ADSL internet with 172.17.231.0/24 lan. The issue is both lan's are in the same building and y need to allow one network to see the other to share ip printers.
I believe i can solve my problem installing a cisco 877 on the adsl side and use one ethernet port to have vlan2 (10.10.10.0/24) and make traffic with that destination route to that port. i tried with no luck. But now i'm thinking it's not possible
my route lines

ip route 0.0.0.0 0.0.0.0 Dialer0
ip route 10.10.10.0 255.255.255.0 Vlan2

thanks

Not quite clear, do understand that you have 2 lans and you want to make 'em communicate to each other. Can you draw up a quick diagram here in this text box itself?

Cheers,

what i really need it's to allow trafic from 172.17.231.0/24 to 10.10.10.0/24 but any other destination go thru internet ADSL and vice versa allow trafic from 10.10.10.0/24 to 172.17.234.0/24 but other one go thru dedicated internet. By the way outside trafic from cisco 877 can't pass to 10.10.10.0/24 (well that's my issue)

How about this;

This way, you'll have to assign both the networks on the lan side interface of 877 (use secondary option), so that routing happens there. Can the 877w support this ?
