Regards

The acl on the ASA is incorrect as it needs to mirror image the router, it should just be one line of:

access-list vpn permit ip 172.21.0.0 255.255.0.0 192.168.48.0 255.255.255.0

You would also need to have NAT exemption configured on the ASA as follows:

access-list nonat permit ip 172.21.0.0 255.255.0.0 192.168.48.0 255.255.255.0

nat (inside) 0 access-list nonat

Please clear the tunnel: clear cry ipsec sa

and "clear xlate" to clear the existing translation.
