Remove this command and try connecting again:

crypto dynamic-map outside_dyn_map 20 set pfs group1

If still does not work, then post the output of:

sh cry isa sa

sh cry ips sa

To check if the ASA is receiving packets and sending packets through the tunnel.

Your split-tunneling list looks like this:
access-list split-tunneling extended permit ip 192.168.100.0 255.255.255.0 192.168.100.0 255.255.255.128

Should look like this:
access-list split-tunneling extended permit ip 192.168.1.0 255.255.255.0 192.168.100.0 255.255.255.128
