I have a brand new 1841 ISR. I have plugged it in, and plugged one cable into one of our subnets' swtiches (FE0/1 <---> 192.168.43.0) and one cable into the other subnets' switches (FE0/0 <---> 10.10.10.0)

My config is below.

Here is what i get from a "show ip route":

Gateway of last resort is 192.168.43.2 to network 0.0.0.0

C    192.168.43.0/24 is directly connected, FastEthernet0/1
     10.0.0.0/24 is subnetted, 1 subnets
C       10.10.10.0 is directly connected, FastEthernet0/0
S*   0.0.0.0/0 [1/0] via 192.168.43.2
               [1/0] via 10.10.10.1


here is my dilemma.

From a laptop on the 192 network (192.168.43.4) i can ping to any server on the 10 network (10.10.10.40 in this case) but no other traffic will pass.

ping 10.10.10.40:

nslookup:

    timeout was 2 seconds.

telnet 10.10.10.40 3389: (to test if i can remote desktop)
Connecting To 10.10.10.40...Could not open connection to the host, on port 3389:
 Connect failed

All these work from a computer on the 10.10.10.0 network, there is no firewall on the server, and clients on the 192.168.43.0 network can access all of these services using the device i am trying to replace (a cisco ASA where traffic is natted, not routed)

I have run the ip routing command 100000x and i dont know what else to do. Isnt this da** thing just supposed to route between connected subnets automatically?
