I was able to get this working at SeaTac by changing the apparently-
incorrect default route handed out.
Was:
# netstat -nr
...
Active Routes:
Network Destination Netmask Gateway Interface
Metric
0.0.0.0 0.0.0.0 198.134.89.88
198.134.91.5 1
...
Works after running this:
route change 0.0.0.0 mask 0.0.0.0 198.134.88.1
...at least, in the subnet I ended up in:
# ipconfig
...
Connection-specific DNS Suffix . :
airportwifi.net
IP Address. . . . . . . . . . . . : 198.134.91.51
