These servers are setup for coexist for the migration, I can send emails from the 2007 to the 2013 but cant send emails from the 2013 to the 2007.
I setup a new rec conn on the 2007 and put the 2013 servers ip in it..
Is there somethingelse I need?

Make sure that your Receive Connector(s) for port 25 and 2525 are set for Exchange and Legacy Exchange Servers:Default Frontend <SERVERNAME> Receive Connector [FrontendTransport - Port 2525]Default <SERVERNAME> Receive Connector [HubTransport - Port 2525]-saige-

Ok so just to verify what I have now is correct, I setup a rec conn on the 2007 server and a send conn on the 2013 server.
Do I need any  other connectors on either 2007 or 2013?

Send connectors are really simple and don't generally affect delivery as they are just used to provide an outbound path.  It is the receive connectors that allow for incoming connections.

The security for your receive connectors have to allow for Exchange and Legacy Exchange Servers to communicate with them.

Did you check the receive connectors on the 2007 server?

You should not need to create a new receive connector on the Exchange 2007 Server.  Just make sure that your Default <SERVERNAME> connector has the following settings -
•      Status: Enabled.
•      Protocol logging level: None.
•      Connector FQDN: ServerName.forestroot.extension
•      Local server Receive connector bindings: All available IP Addresses. The server accepts mail received through any network adapter on the Hub Transport server.
•      Port: 25.
•      Remote server IP address range: 0.0.0.0-255.255.255.255. The Hub Transport server accepts mail that is sent from any IP address.

Note:

In Exchange 2007 SP1, the IPv6 address range 0000:0000:0000:0000:0000:0000:0.0.0.0-ffff:ffff:ffff:ffff:ffff:ffff:255.255.255.255 also exists for remote servers.

If Exchange 2007 SP1 is deployed on a computer that is running Windows Server 2008, you can enter IP addresses and IP address ranges in the IPv4 format, IPv6 format, or both formats. A default installation of Windows Server 2008 enables support for IPv4 and IPv6. For more information about Exchange 2007 SP1 support for IPv6 addresses, see IPv6 Support in Exchange 2007 SP1 and SP2.  

•      Available authentication methods: TLS, Basic authentication, Integrated Windows authentication.
•      Permission groups: Exchange users, Exchange servers, Legacy Exchange servers.
