Cisco VPN not passing traffic

I am working on a site that has a cisco asa 5505 in the main office with a vpns to it.  They just opened a new remote location and put in a cisco asa 5505 there.  I used the easy vpn wizard at the main site to setup a connection and configured the easy vpn at the remote site.  The vpn is showing that it is connected but no traffic is passing through.  I can see connection active and authentication takes place and they both look normal but that is it.  

Any help would be great.  Let me know if you need further detail

Are the subnets on each end different? They need to be.

Other than that, enable logging on both end, make the connection, and then what is in the logs about traffic.

You may need to enable NAT Traversal, but normally that affects the connection as well.

yes both on are different subnets.  I have logging on but I don't see it blocking any traffic.  I am trying to find any denies.  I am assuming there are some rules I would need to put in the firewall for it but I am not sure what that would be.

I use Juniper boxes for most clients, and there is a specific policy to permit VPN traffic both ways. I don't know what the counterpart is on a commercial Cisco box.

got the vpn passing traffic by putting in some firewall rules.  Now the remote location can get to the main site but cannot get out to the internet!

I set a remote site Juniper so that the remote site uses internet via its own connection (not the home site internet). I don't think you should try to route remote internet through the home site as it will be slow.

Can you implement "split tunneling" at the remote site? That will let it use its own internet.

I am not exactly certain (because I employ Juniper instead) but I would think yes. Each end wants its own internet. I assume you are using IPsec.

split tunneling is the answer I just can't figure out how to configure it, Cisco is not my friend today.

There is a Cisco Support article for Split Tunneling in Easy VPN.

http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a0080809222.shtml

It is a few lines down from the beginning of the configuration example.  I don't know if this applies to you as I am not a Cisco expert at all.
