In removing the Host-Uniq tag, I see the following on the wire: cerebus:~# tcpdump -nev -s 256 ether proto 0x8863 or ether proto 0x8864 tcpdump: listening on de0 23:23:18.010000 0:c0:f0:22:35:e1 ff:ff:ff:ff:ff:ff 8863 24: 1109 0000 0004 0101 0000 23:23:18.728783 0:10:67:0:3c:ee 0:c0:f0:22:35:e1 8863 61: 1107 0000 0029 0101 0000 0102 001d 3133 3034 3130 3439 3931 3833 3632 2d73 6d73 322d 746f 726f 6e74 6f36 3301 0100 00 23:23:19.005733 0:c0:f0:22:35:e1 ff:ff:ff:ff:ff:ff 8863 24: 1109 0000 0004 0101 0000 23:23:19.728640 0:10:67:0:3c:ee 0:c0:f0:22:35:e1 8863 61: 1107 0000 0029 0101 0000 0102 001d 3133 3034 3130 3439 3931 3833 3632 2d73 6d73 322d 746f 726f 6e74 6f36 3301 0100 00 As you can see, I can now elicit a PADO from Sympatico. Unfortunately, it looks like removing the Host-Uniq tag breaks all that code which uses the Host-Uniq identifier to match which flow belongs to which node.
