Lynwood, what I see happening is your IPIP packets coming in, and decapped traffic going out:
17:03:08.012996 IP (tos 0x0, ttl 62, id 62733, offset 0, flags [none], proto UDP (17), length 63, bad cksum 0 (->c529)!) 44.60.44.3.41269 > 208.80.153.231.53: 53665 A? www.mediawiki.org. (35)
They all seem to be queries to DNS servers. Are you getting any responses? - Brian
