SSL VPN - Can Connect But No Traffic

Having quite a bit of difficulty configuring SSL VPN. I can now successfully establish an SSL VPN connection through the client (I get the green light) and confirm that I get assigned an IP from the SSL VPN pool. But I cannot connect to anything at all. When I try pinging the firewall (or any other IP address on the LAN) I get no results. When I turn on default gateway, I cannot access any external websites. It's like it's connected to nothing at all.

Even more odd is that the firewall rule I created shows traffic coming through:

And the logs also show traffic as being allowed:

I've followed the "Configuring SSL VPN for Remote Access" guide and have checked and rechecked my settings.

I also found another discussion that suggested a new host network be created and interface ports be deleted from the VPN config (Configure - VPN - SSL VPN (Remote Access), so I did that:

I've defined LAN as the entire subnet I'm using for the LAN:

SSL VPN settings have been left at the defaults, other than changing encryption to AES-256-CBC.

I've not bothered posting the other SSL VPN settings seeing as how I can establish the VPN connection.

This is driving me nuts. Might anyone have any suggestions as to what I might be doing wrong?
