As you can see, mtu is 1392. So any attempt to open big content from site or download a big file will fail. tcpdump shows:

14:13:09.876867 172.16.1.2 > 217.106.231.104: icmp: 192.168.0.168
unreachable - need to frag (mtu 1392) (DF)
...and so on.

Try tcpmssd from ports, and bind it to ng0 after it comes up. It should diddle the MSS values in your TCP SYNs on the fly. (You may also have to do something similar on the tunnel endpoint for inbound connections.)
