Site-to-site VPN tunnel between Pix 506E and Linksys RV042

I have created an ipsec tunnel between my pix 506e and a linksys rv042.  The tunnel establishes just fine, but no traffic will flow over it.  This is my first time doing this, and I would like to know if I have configured something incorrectly on my pix.  Here is the config:

So you only want the subnet to go across the VPN tunnel to the Linksys?
Does the router that is know to route traffic destined for over to the PIX?
What is result of "show cry is sa"
If you see nothing, look at result of "show access-list" if you get zero hitcounts on your chicago vpn access-lists, then you have a routing issue.
If you see QM_IDLE you should be golden
If you see MM_NO_STATE you may have a policy mismatch. Make sure PFS is not enabled on the Linksys.
If you see MM_KEYEXCHANGE try the command again in a few seconds.

Any particular reason you are using DES and Group 1 vs 3DES and group 2 ?

The subnet is good enough for now, just to make sure it's working.  The router has the pix as its default gateway.  Is that good enough for it to properly route the traffic destined for back to the pix, or do I need to explicitly specify a route?

When I do a sh cry is sa I get QM_IDLE, and the hitcounts are going up for the chicago access-lists.

I was just using DES and Group 1 as opposed to 3DES and Group 2 for performance - is there a big difference?  Do you think that would be preventing the traffic for any reason?

Thanks for your help.
Hmmmm....looks like everything "should" be working.
Default pointing to PIX should be all you need.
Do you get "connected" indicator on the Linksys side?
Is the Linksys LAN IP the default gateway for everything on that end?
Look at "show cry ip sa" and look for encrypt/decrypt counters and error counters.
increasing counters on encrypt/decrypt means traffic is indeed flowing between the two networks.

There should not be a performance hit with either DES or 3DES. If you have the 3des license you might want to consider using it later, but just get them working now..

DOH! I missed this little tidbit earlier:
>route inside 1
Since the remote side falls within this mask, you've got a routing loop pointing back to the other router.
 no route inside 1
 route inside
