Wireless to lan routing issue

Installing and Using OpenWrt Network and Wireless Configuration
1

i am trying to setup a portable wireless ap that uses the ethernet port as a client but allows other (wireless) clients to connect to it (using a different). i want the wireless clients to see the whole network and access the internet but the rest of the network should only see the tplink tl-wr802n router as a client, everything seems to me like it is set up but the wireless clients (192.168.64.0/25) cant access the internet, the router with the lan setup as as a dhcp client (192.168.1.42) itsself does connect

There is no mention of the wifi network in the firewall, so it is all going to be blocked.

You don't actually need a new network here, you could use conventional lan->wan NAT and route. The WAN holds one IP on the upstream network and masquerades all the wifi users to that IP. If a wifi user knows the IP of a device on the upstream network, they can access it through the default route the same way as going to the Internet. It sounds like you want that, but if not the firewall can be configured to block it.

The only issue with that is that the wifi users are on the trusted lan network and would be difficult to blocked from attempting to log into OpenWrt. If that is a problem, set up a separate network using the guest network directions. Then you'd forward from guest to wan.
