Default WiFi at Sea (technical, sorry)

Wow,
this whole thread is pretty whacked, or funny, depending on your
perspective.

Skip needs a new access point.
one that will allow him to set the SSID so that he can specifially
attach to it. The lastest issue is that Skip is NOT accessing his local
lan locally, he is accessing it via the foreign access point. In fact,
technically, the foreign access point is his local lan.
poor skip.

Wayne has the right idea, just stop doofing around and do it. AND, if
you REALLY want to have fun, you can go to http://openwrt.org and
install Linux on your WRTG and get all sorts of fun features! (please
don't).

As for me, I went to www.hacom.net and purchased a little black box and
put linux on it, then you can install whatever card you want, my unit
has 4 usb ports, 2 pcmcia, etc. I use it to connect to the internet via
my Verizon 7130e over their EVDO network, nnnnoice. Its an awesome
router/boat controller. But I digress.

anywho, if you know what you are donig, roll your own, if you dont,
PLEASE listen to Wayne and be done with it. Look, you spend how much on
fuel and rum? Just buy the silly wrtg. Oh you want it on your mast for
better coverage? Why? WRTG's are cheap by 3 of them, in fact, they are
disposable, by 4, just in case one dies.

This is incorrect. A router with sufficient features can redirect whatever
it likes. It's quite common for hotspot types of setups to do just that.
So it doesn't matter if you have a static address, vpn or anything else.
Any packets that hit the router can be manipulated to return anything the
router dictates. Even at the ARP level. So your machine does an ARP lookup
trying to find your static address (or route) and it's given the router's
address; this is normal. But at the same time the router now knows your MAC
address (also normal). You use your browser and your MAC address then sends
other packets, the hotspot router understands this as HTTP traffic and
returns the redirected HTML content. Try any other static addresses and
you'll get the exact same thing.YES, but if Skip is attempting to access (port 80 HTTP) an IP address

LOCAL TO HIS ONBOARD LAN, *HOW* is the router at the hotspot
intercepting it? It shouldn't have any interest in any local addresses
on the LAN side of Skip's bridge. You obviously have a better than
obvious grasp of what's going on so can you provide an explanation or
suggest the next troubleshooting step Skip should try?
